36 VÖGELE Pavers Build North Africa’s<br />

New Life Line<br />

The world’s currently largest road construction project is not underway in Europe,<br />

in North America or in Asia but – as many will no doubt be surprised to hear – in<br />

North Africa. In the last few years, the region has seen increasing economic success.<br />

Now it is time to expand the infrastructure in order to stay on the route of growth.<br />

And this is why a motorway is to connect the “Magreb” states of Morocco, Algeria<br />

and Tunisia over a stretch of 3,200km from 2009. The construction work for the<br />

“Autoroute Transmaghrébine” is well underway in Algeria, where three consortia are<br />

building their motorway section of around 1,200 kilometres. A whole fleet of machines<br />

from the WIRTGEN Group is involved in the giant project, including 36 SUPER pavers.<br />

Much has occurred since the launch of the VÖGELE InLine Pave ® concept. In Europe,<br />

some 1,500,000m 2 of road pavement have meanwhile been built with InLine Pave ®<br />

machinery. This innovative method is primarily used for rehabilitating motorways, federal<br />

highways or rural roads in single-lane or dual-lane width, but also for constructing new<br />

roadways. Again and again, the extremely high compaction of the binder course is in the<br />

focus of the “hot on hot” paving method. InLine Pave ® has become such a major topic<br />

that we are devoting a special edition of RoadNews to the innovative and economical<br />

technology.<br />

Widening of the Swiss A 4 trunk road to four lanes with NAVITRONIC Plus ® .<br />

Construction of Motorway without<br />

Tensioned Wire but with Swiss Precision<br />

The A 4 trunk road in Switzerland only had two lanes in the Zürch Weinland region. In the light of increasing<br />

volumes of traffic, the decision was made to widen the 20km section concerned to a four-lane motorway with<br />

separated carriageways for each direction. Swiss contractor Implenia AG used a SUPER 2100-2 paver equipped<br />

with NAVITRONIC Plus ® , the 3D System for Machine Control developed by VÖGELE.<br />

Focus on NAVITRONIC Plus ® .<br />

3D Navigation in a Virtual Space<br />

At Bauma 2007, the German International Fair for<br />

Construction Machinery, VÖGELE presented a true<br />

innovation with NAVITRONIC Plus ® , the 3D System for<br />

Machine Control. The system developed from scratch<br />

features an “Open Interface” allowing to connect 3D<br />

positioning systems, such as laser-based total stations or<br />

GPS, from numerous well-known manufacturers. As a vital<br />

aspect, NAVITRONIC Plus ® is easy to understand and<br />

operates very conveniently. And it offers another unique<br />

advantage. As a real 3D system, NAVITRONIC Plus ® not<br />

only controls fully automatically the pavement’s grade and<br />

slope but also the screed’s position and the paver’s<br />

direction of motion. Survey data collected for earthworks,<br />

for instance, can be used for asphalt paving as well. This<br />

substantially boosts the system’s economic efficiency.<br />

RoadNews reports on two job sites where SUPER pavers<br />

were operating with NAVITRONIC Plus ® . And we demonstrate<br />

in an example how easily and quickly the system installs.<br />

With an average traffic volume of 20,000 to 25,000 vehicles<br />

per day, the A 4 trunk road between Winterthur and<br />

Schaffhausen was one of the busiest two-lane stretches.<br />

Trunk roads of this kind usually are built without crossroads.<br />

In contrast to motorways, however, they do not have<br />

separated carriageways for each direction in most of the<br />

cases. Therefore, the Federal Council of Switzerland in Bern<br />

planned an enlargement of the dual-lane A 4 trunk road to a<br />

four-lane mini-motorway. Mini-motorways are a Swiss<br />

particularity and, in contrast to regular motorways, built<br />

according to diminished standards. These mini-motorways,<br />

for instance, feature narrower carriageways and do not have<br />

hard shoulders the whole length.<br />

NAVITRONIC Plus ® a premiere for the paving team<br />

6<br />

The major construction job represented a premiere for the<br />

paving team of contractor Implenia AG, who were working<br />

with the NAVITRONIC Plus ® 3D Machine Control System for<br />

the first time ever. Once the system had been installed on the<br />

Construction of motorway lanes without tensioned wire:<br />

NAVITRONIC Plus ® the 3D System for Machine Control,<br />

guides the SUPER 2100-2 towards highly accurate paving results.<br />

SUPER 2100-2, the team familiarized themselves with the<br />

technology. After all, the task was to place the foundation layer<br />

and base course for the new lanes on the basis of a 3D model<br />

without using a physical reference.<br />

Foundation layers are bound base courses which, in the main,<br />

are made of recycled material. For the A 4, a hot-mixed<br />

foundation course was placed with a share of recycled aspalt<br />

ranging between 50 and 60%.<br />

On this job site, NAVITRONIC Plus ® was combined with<br />

positioning equipment from Leica. Based on the route’s digital<br />

design data, this technology picks up the paver’s actual position<br />

by a total station and a 360° prism. High-precision sensors<br />

installed on the paver suppy extra information on the screed’s<br />

elevation and slope as well as the screed’s position. The entirety<br />

of data collected is passed on to the positioning system’s<br />

external computer and a comparison is made with the route’s<br />

stored design data. Any deviations detected are finally<br />

transmitted to NAVITRONIC Plus ® , which initiates a correction.

metres, it was evident that the Implenia team had a perfect<br />

command of NAVITRONIC Plus ® . Furthermore, it was no<br />

problem at all to meet the specified tolerance requirements<br />

of +/-4mm. Placing the foundation layer and base course<br />

in a large width up to 9m turned out to be easy game for<br />

the paving team. And this was predominantly due to the<br />

VÖGELE 3D Machine Control System. The site manager<br />

was extremely enthusiastic: “We certainly didn’t miss<br />

not working with a tensioned wire. Quite the opposite,<br />

in fact!” ,<br />

SUPER 1800-2 rehabilitates a runway and landing strip in Iceland.<br />

NAVITRONIC Plus ®<br />

Saves 18km of Tensioned Wire<br />

SITE REPORT 2<br />

NAVITRONIC Plus ®<br />

The company operating Akureyri Airport planned an extension with the aim of enticing more tourists to Iceland.<br />

To this end, the runway and landing strip had to be lengthened and the existing section rehabilitated so that larger<br />

aircraft could also land. In a first step, Icelandic contractor Hladbaer-Colas rehabilitated the old runway. Undulating<br />

surface irregularities had developed over the years, and height differences of as much as 20cm needed to be levelled<br />

out in the course of the rehabilitation work. Hladbaer-Colas decided to use NAVITRONIC Plus ® , the VÖGELE System<br />

for 3D Machine Control, in order to achieve as level a surface as possible.<br />

with<br />

SBG Computer<br />

With a population of 17,000 inhabitants, Akureyri is Iceland’s<br />

fourth largest town and the most important service centre<br />

in the north of the country. The numerous wool and fish<br />

processing enterprises are of great economic significance.<br />

However, Akureyri Airport is not only important for the<br />

economy, but also increasingly so for tourism. Therefore,<br />

the initial stage of the project involved rehabilitating<br />

the runway and landing strip, with the extension planned<br />

for the year after.<br />

Level regulating layer provides for uniform base<br />

10<br />

Before the paver’s actual work could commence,<br />

a compact WIRTGEN W 350 Cold Milling Machine removed<br />

roughly half of the 20cm surface undulations. The paving<br />

team then placed a 10cm level regulating layer with their<br />

SUPER 1800-2 combined with an AB 500-2 TV Extending<br />

Screed. The material used for this layer was open-graded<br />

asphalt (0/16) with a binder content of 5.7%.<br />

Hard granite imported from Norway<br />

The level regulating layer was followed by wearing course<br />

placed in widths between 4 and 5m. Paving in varying width<br />

was done for good reason in order to avoid creating the<br />

longitudinal joints of this course right above those of the level<br />

regulating layer. For wearing course, too, an open-graded<br />

asphalt was used with a grain size of (0/11). The aggregate<br />

contained in this mix was granite, which due to its hardness<br />

is particularly strong and long-lasting. The granite had been<br />

imported from Norway as the rock of the volcanic island, due<br />

to its porous nature, is not suited as an aggregate for asphalt<br />

paving. Altogether, the Hladbaer-Colas team placed nine<br />

strips, always working from the outside in. Each of the 2,000m<br />

strips had to be completed in just one day so that the runway<br />

could be used for air traffic the following morning.<br />

As far as surface evenness was concerned, < 3mm<br />

were specified in both the longitudinal and the transverse<br />

directions, over a distance of 3m. In order to precisely comply<br />

with the desired accuracy, Hladbaer-Colas relied on<br />

NAVITRONIC Plus ® , the VÖGELE System for 3D Machine<br />

Control. They combined the system with a SBG external<br />

computer and tachymeters from Leica. On the job site in<br />

Iceland, the use of NAVITRONIC Plus ® yielded major<br />

advantages: without 3D machine control, reference wires<br />

would have had to be installed. This way of proceeding would<br />

not only have been more costly, but also extremely difficult<br />

and time-consuming. On account of the air traffic, installing<br />

the wires was not possible in advance but only at the start<br />

of work. All told, at least 18km of reference wire would have<br />

been required at an estimated cost of some 50,000 Euros.<br />

The 45m wide runway and landing strip at Akureyri Airport.<br />

SUPER 1800-2 and HAMM DV 70 VO ensure paving<br />

on schedule<br />

The overall width of the runway and landing strip at<br />

Akureyri Airport is 45m. Added to this are hard shoulders,<br />

7.5m wide on each side, yielding a total width of 60m.<br />

The SUPER 1800-2 paved wearing course in a thickness of<br />

5cm. After completion, two DV 70 VO tandem rollers from<br />

HAMM joined in. Weighing around 8 tonnes and equipped<br />

with oscillation technology, the rollers compacted the<br />

asphalt to perfection. The pavement profile specified in<br />

both the longitudinal and the transverse directions, too,<br />

was met with high accuracy thanks to NAVITRONIC Plus ®.<br />

Beyond all that, the NAVITRONIC Plus ® solution for machine<br />

control offers a unique advantage: as a real 3D system, it not<br />

only controls fully automatically the pavement’s grade and<br />

slope, but also the screed’s position and the paver’s direction<br />

of motion. ,<br />

Installation of the VÖGELE 3D Machine Control System.<br />

How to Install<br />

NAVITRONIC Plus ®<br />

in 10 Easy Steps<br />

Even a modern 3D Machine Control System can be<br />

installed easily. This is what VÖGELE want to<br />

demonstrate in the following for NAVITRONIC Plus ® .<br />

The system installs as easily as it operates. RoadNews<br />

shows in 10 steps how to fit the system to the paver<br />

and how to prepare it for paving.<br />

Overview of the NAVITRONIC Plus ® components<br />

to be installed on the paver:<br />

n Holder for mast<br />

n Sensor for screed width<br />

n Magnetic holder<br />

n Screed operator’s console<br />

n Sensor for mast inclination<br />

n Connecting cable<br />

The steps earmarked with this symbol are to be<br />

carried out prior to every paver operation. All other<br />

steps need to be carried out only once, i.e. when<br />

installing NAVITRONIC Plus ® .<br />

1 Fitting the Holder for the Mast<br />

The bracket serves as a holder for the mast and the<br />

receptor fitted to it. The receptor can be a GPS receiver,<br />

laser receiver or prism. See to it that the bracket is<br />

positioned above the paver’s augers and aligned<br />

parallel with the flange joining screed and screed arm.<br />

With some systems, two receptors can be used. In such<br />

a case, two masts need to be fitted (left and right sides).<br />

2 Fitting the Sensors<br />

Attach the clamps of the sensors for screed width in the<br />

places provided for them using the screws supplied.<br />

Important: For initial set-up, the sensors should slide<br />

smoothly in the clamps.


Some positioning systems need information on the<br />

inclination of the mast. To collect these data, a sensor<br />

picking up the inclination needs to be attached to the<br />

mast holder.<br />

Then fit the 3D receptor to the mast and attach the mast<br />

to the holder. See to tight fit in order to prevent the mast,<br />

including receptor, from swaying while paving.<br />

3 Connecting the Cables<br />

Connect the cables before switching on the paver’s<br />

ignition. Plug the cable of the sensor for screed width and<br />

the one of the sensor for inclination of the mast into the<br />

screed operator’s console.<br />

4 Measuring the Mast’s Position (3D Receptor)<br />

In order to create a digital machine model, the precise<br />

position of the 3D receptor must be measured in relation<br />

to the screed.<br />

5 Defining the Working Range<br />

As a function of the desired pave width, a working range<br />

needs to be defined. This should cover the pave width<br />

+/-40cm (+/-20cm on either side of the screed).<br />

Example: For a desired pave width of 5.8m, the limits<br />

“MAX 6.2m” and “MIN 5.4m” would have to be selected.<br />

This working range is necessary in order to correct<br />

deviations in the paver’s position from the design route<br />

by moving the screed’s extending units in or out.<br />

For the desired pave width of 5.8m described above, the<br />

example shows an AB 500-2 Extending Screed fitted with<br />

a set of 75cm bolt-on extensions.<br />

750 5000<br />

6 Setting up the Sensors for Screed Width 7 Calibrating Screed Width Control<br />

Extend the screed to the desired pave width of 5.8m.<br />

Then slide the sensors for screed width, guided by<br />

the clamps, into place.<br />

The sensors should be positioned in such a way that<br />

their measuring range is not left when moving the<br />

screed’s extending units in or out. The measuring range<br />

is indicated by two marks on the sensor. The sensors<br />

must not touch each other when retracting the screed.<br />

Then tighten the screws to firmly attach the sensors<br />

to the screed.<br />

Now fit the magnetic holders right above the sensors.<br />

The clearance between the magnet and the sensor<br />

should be 2mm and not exceed a maximum of 4mm.<br />

After installation of the sensors is completed and all<br />

cables are connected, the screed needs calibrating.<br />

Calibration is necessary every time the screed<br />

configuration or sensor position has been changed.<br />

To perform the calibration, just go to the screed<br />

operator’s ErgoPlus ® console and access the<br />

NAVITRONIC Plus ® calibration menue. Define the<br />

working range, which is your desired pave width<br />

+/-40cm (+/-20cm per side). In our example, the range<br />

extends from “MIN 5.4m” to “MAX 6.2m”. The working<br />

range sets the limits for screed width control.


8 Moving the Paver to the Starting Line 9 Setting up the Screed’s Elevation and Width<br />

Before moving the paver to the starting line, the external<br />

3D system must have been installed and connected<br />

to NAVITRONIC Plus ® . Only then is it possible to pick<br />

up the paver’s actual position and to calculate the<br />

specified position.<br />

The next step is to select, on the display of the paver<br />

operator’s ErgoPlus ® console, the 3D sensor for<br />

automatic steering.<br />

Now the machine’s actual position is displayed on the<br />

paver operator’s ErgoPlus ® console. He can manoeuvre<br />

his machine to the starting line.<br />

The paver should be positioned on the steering line<br />

as accurately as possible (±5 to 10cm). In our example,<br />

the paver is positioned 10cm to the right of the steering<br />

line. Display of a positive value means, the paver’s<br />

position is to the right of the line. A negative value<br />

indicates a paver position to the left of the line.<br />

Now lower down the screed and roughly set the<br />

screed’s tow points to the desired height. From this<br />

setting, a screed planing angle results. For being able<br />

to work with digital data, select “3D” as a grade sensor<br />

(use F2 and F4 keys on the screed operators ErgoPlus ®<br />

console).<br />

The external positioning system picks up a difference in<br />

height and transmits this information to NIVELTRONIC Plus ® .<br />

The deviation is displayed by the system. It may be<br />

necessary to place timber under the screed for height<br />

correction until the deviation lies within the range of just<br />

millimetres.<br />

10 That’s it ! Mix, please !<br />

When all axes – X, Y and Z – are set up, you can commence<br />

paving.<br />

Quick and Easy:<br />

Mounting Bolt-on Extensions<br />

to VÖGELE Extending Screeds<br />

All VÖGELE screeds can be built up using bolt-on extensions,<br />

tailoring them to any desired pave width. The VÖGELE<br />

system of bolt-on extensions allows quick and stable<br />

build-up of the screeds to meet the requirements of the<br />

contractors’ paving jobs. In this issue of Tips & Tricks,<br />

André Felchner demonstrates how easy it is to mount<br />

bolt-on extensions.<br />

andré felchner, Head of applications Technology at VÖGElE, Germany, provides “Tips & Tricks from practical<br />

applications”. He is an expert in both practical applications and paver technology and conveys his knowledge<br />

also in VÖGElE training courses and workshops to paving teams from all over the world.<br />

1<br />

Day-to-day life on the job site rarely provides level<br />

ground conditions. However, a level surface is<br />

required for mounting bolt-on extensions. In order<br />

to compensate for unevenness, large pieces of<br />

square timber or pallets can be placed under the<br />

screed. Care must be taken that the flanges are<br />

clean, i. e. no asphalt sticking to them.<br />

TIP!<br />

Preparation<br />

Before mounting a bolt-on extension, the<br />

tamper shafts of both the screed’s extending<br />

unit and the bolt-on extension must be set<br />

so that the arrow on the coupling points at<br />

the gap in the gearwheel. (see photo).

The beveled quick-fitting aid (equipped on all “dash 2”<br />

generation screeds), allows quick and easy attachment<br />

of the bolt-on extension. Thanks to the quick-fitting aid,<br />

the extension can already be raised at this stage,<br />

without a need for bolts to be fastened.<br />

TIP!<br />

The front and rear eccentric bolts have to be<br />

set to zero, which is the uppermost position.<br />

This is important later on for aligning the bolt-on<br />

extension with the screed’s extending unit.<br />

Now the bolt-on extension needs adjusting in height<br />

to match the screed’s extending unit. Set it to the<br />

correct height by using the eccentric bolts.<br />

Please note: “Correct height” means that the bolt-on<br />

extension and the screed’s extending unit are set<br />

to identical heights and are properly aligned.<br />

The rear edges of the screed plates shall be flush.<br />

The front edges of the screed plates should be set<br />

between 0.5 and 1mm higher.<br />

4 Fitting the Braces<br />

5<br />

After having carried out the adjustments of Step 3,<br />

the frames of the screed's extending unit and of the<br />

extension must be bolted together.<br />

Then fit the braces serving to stabilize the bolt-on<br />

extensions. These braces shall be adjusted so that<br />

a light downwards pressure is exerted onto the<br />

extension.<br />

TIP!<br />

The pressure is correct if the brace can<br />

be turned slightly. If it cannot, the pressure<br />

is too high.<br />

Connecting Systems<br />

As a next step, connect electric screed heating<br />

(see photo, left).<br />

Then join the tamper shafts of the bolt-on extension<br />

and screed’s extending unit by means of the Haldex<br />

coupling (see photo, right).<br />

The following steps only need to be carried out when<br />

fitting bolt-on extensions to VÖGELE High Compaction<br />

Screeds with 1 or 2 pressure bars (TP1 or TP2).<br />

Please continue after Step 5 on the previous page.<br />

The pressure bars P1 and P2 of the bolt-on extension<br />

and those of the screed’s extending unit must be<br />

joined. This is done by using bolts with spring washers<br />

and a spacer. The rear edges of the pressure bars<br />

of the bolt-on extension and of the screed’s extending<br />

unit shall be flush. The pressure bars’ edges, when<br />

touching from below, must be flush too (see photo).<br />

Then check the pressure bars for smooth and free<br />

movement.<br />

Special tools for joining the pressure bars:<br />

The tools required are a standard ratchet,<br />

a hexagon adaptor (Order No. 2124649) and<br />

an Allan key (Order No. 46,2210,0002).<br />

The Shao Yong Expressway will be an important link in China’s<br />

long-distance transportation network and is of immense<br />

strategic importance to the Central Kingdom. The 110km<br />

stretch between the mega cities of Shaoyang and Yongzhou<br />

is part of the 1,738km long north-south axis from the city<br />

of Taiyuan to the gambling paradise of Macau. The new<br />

connection, running in parallel, is intended to relieve the<br />

expressway between Beijing and Zuhai, which winds more<br />

than 2,290km through China. The expressway is known as<br />

a traffic congested route.<br />

With ErgoPlus ® on board, the operator enjoys an unobstructed view of all<br />

vital points on the paver, such as material hopper, auger and screed.<br />

800,000 tonnes of CTB needed<br />

The project kicked off in May 2006 with the placing of<br />

cement-treated base. In order to establish a foundation of high<br />

load-bearing capacity for the roadway, the CTB base was<br />

amply dimensioned and made up of three layers: the first<br />

one 20cm thick and the two following layers 19cm each.<br />

For the road base alone, 800,000 tonnes of CTB were<br />

required, prepared in eight mixing plants. Supply of the pavers<br />

with mix had been minutely planned by contractor Guangdong<br />

Liantai Group: the capacity of each mixing plant was 500t per<br />

hour and up to 10 haul vehicles per plant transported the mix<br />

to the job site to feed the pavers.


The SUPER 2100-2 with High Compaction Screed achieved an excellent degree of density<br />

when placing thick base course.<br />

A strong foundation: Cement-treated base (CTB)<br />

The function of a base course is to provide a uniform foundation<br />

of high stability for the layers placed on top, such as asphalt<br />

binder course and asphalt wearing course. In combination with<br />

these layers, the base absorbs the forces from traffic and<br />

provides for uniform distribution of these forces onto the<br />

sub-base. The purpose of the base course also is to ensure<br />

quick and effective protection of the sub-base against water<br />

to maintain its load-bearing capacity.<br />

Base courses are often built as cement-treated bases (CTB).<br />

These bases are well proven in road construction. The mixes<br />

prepared in mixing plants are transported to the job sites by lorries.<br />

In the event of long distances for transport to the job site<br />

or adverse weather conditions, the CTB should be covered<br />

with tarpaulins. It is recommended to use pavers with high<br />

compaction screeds for placing the mix. The advantage: these<br />

screeds achieve a high degree of pre-compaction. In order<br />

to obtain a perfect bond between several layers, these layers<br />

should be placed “fresh on fresh”. For final compaction of<br />

cement-treated bases, rubber-tyred rollers and/or single-drum<br />

compactors are generally used.<br />

Two SUPER 2100-2 demonstrate superior performance<br />

The Shao Yong Expressway is being built with four lanes in<br />

each direction, which sums up to a total width of 52m.<br />

For the paving operations, contractor Guangdong Liantai<br />

Group Co., Ltd. opted for pavers from VÖGELE. The two<br />

SUPER 2100-2 were combined with SB 250 Fixed-Width<br />

Screeds in TP1 version. The pave width was 13m and covered<br />

two lanes. Placing the CTB went smoothly, not least thanks<br />

to the well-thought-out and proven machine concept of the<br />

“dash 2” generation VÖGELE pavers. With its powerful engine<br />

delivering 182kW, the SUPER 2100-2 is a true workhorse.<br />

And the material hopper, conveyors and augers, too, are<br />

designed for high laydown rates. A SUPER 2100-2 is capable<br />

of placing up to 1,100 tonnes of mix per hour. This performance<br />

makes the machine the perfect choice for large job sites<br />

such as the Shao Yong Expressway, a task handled by the<br />

powerful paver economically and with ease.<br />

High Compaction Screeds get the job done<br />

On the Shao Yong Expressway site, the two SUPER pavers<br />

impressively demonstrated that the choice of VÖGELE<br />

equipment was precisely the right decision. When placing<br />

cement-treated base, the VÖGELE High Compaction Screeds<br />

achieved perfect results in terms of pre-compaction and<br />

accuracy of levels. Cement-treated bases consist of unbroken<br />

and /or broken aggregate bonded with cement, a hydraulic<br />

binder. SUPER pavers are capable of placing these materials<br />

in a perfect manner, as they demonstrated on the Shao Yong<br />

Expressway. The SB 250 Fixed-Width Screed in TP1 version,<br />

equipped with one pressure bar driven by pulsed-flow<br />

hydraulics, achieved a first-class degree of pre-compaction.<br />

10 HAMM rollers produced the final density<br />

As for the earthworks, HAMM Series 3000 rollers were<br />

also used for final compaction of the cement-treated base.<br />

As many as 10 units of the orange coloured HAMM machines<br />

were on the scene. The Series 3000 rollers combine modern<br />

technology with outstanding design and lots of comfort.


Contractor much impressed by WIRTGEN products<br />

and service<br />

Guangdong Liantai Group Co., Ltd. are highly satisfied<br />

with the performances of all equipment involved and also<br />

with the service provided by WIRTGEN China. When this<br />

large-scale project came up, those responsible in the<br />

company had decided in favour of products from VÖGELE and<br />

HAMM. The use of machinery from the WIRTGEN Group has<br />

a long tradition with the construction company. Guangdong<br />

Liantai Group already completed a great number of projects<br />

Teamwork: 2 VÖGELE pavers and 10 HAMM rollers<br />

worked together successfully on the Shao Yong Expressway<br />

job site in Hunan province.<br />

with VÖGELE pavers to their entire satisfaction. Now the<br />

asphalt layers are still due for paving. For this job, too, the<br />

two VÖGELE SUPER 2100-2 will play the key role. On the<br />

cement-treated base, they are going to lay 10cm asphalt<br />

base, 6cm binder course and 5cm wearing course. After<br />

an incredibly short construction time of just 3 years, the<br />

Shao Yong Expressway will be opened to traffic in 2009.<br />

The new 110km stretch will pass over 90 bridges and<br />

through 17 tunnels. ,<br />

Some 70 machines from the WIRTGEN Group are involved in the world’s currently largest road construction project.<br />

SUPER Power for the<br />

“Autoroute Transmaghrébine”<br />

North Africa has developed into a veritable boom region in recent years. In order to maintain this growth, huge<br />

investments are currently being made in a gigantic road construction project. “Autoroute Transmaghrébine” is the name<br />

of the largest African road building project ever and, for the time being, the largest in the world. Once completed, the<br />

motorway is planned to connect the Maghreb states of Morocco, Algeria, Tunisia and Libya over a stretch of more than<br />

3,200km. The construction work is already well on its way in Algeria, where three consortia were awarded the contracts<br />

for building 1,200 kilometres of the motorway. Numerous machines from the WIRTGEN Group are also being employed<br />

for this project, including 36 VÖGELE pavers, 30 HAMM rollers and WIRTGEN slipform pavers for building the concrete<br />

crash barriers.<br />

24


Contractors from the world over involved<br />

26<br />

Three construction consortia are involved in the building<br />

of the 1,200km Algerian stretch of the “Autoroute Transmaghrébine”.<br />

The eastern section running from the Algerian city<br />

of Bordj-Bou-Arreridj to the border with Tunisia is being built by<br />

the Japanese consortium COJAAL. A subsection around Algiers<br />

is executed by Algerian contractors ALTRO and COSIDER, while<br />

the rest of the section is handled by the Chinese consortium<br />

CITIC-CRCC. Many additional companies from all over the<br />

world are also involved in the construction of bridges, tunnels<br />

and drainage systems, etc. The capital investment for the job<br />

site in Algeria alone totals USD 11 billion.<br />

Stringent requirements on quality<br />

A high volume of traffic is anticipated on North Africa’s new<br />

“life line”. Therefore, the “Transmaghrébine” motorway is being<br />

constructed in Algeria with three lanes in each direction. What’s<br />

more, high requirements are made on pavement quality,<br />

especially in terms of resistance to deformation. To ensure that<br />

the high standards will be met, all SUPER pavers participating in<br />

the construction of the motorway are equipped with VÖGELE<br />

High Compaction Screeds.<br />

Paving “hot to hot“: A total of 25 tracked VÖGELE SUPER 2100-2 pavers<br />

participate in the building of the “Autoroute Transmaghrébine”.<br />

The “Autoroute Transmaghrébine” over the entire 1,200km<br />

stretch is designed as follows: base course of cement-treated<br />

gravelly sand is placed in a thickness of 20cm, followed by<br />

a 14cm bituminous bound base, with the road finally being<br />

surfaced with a wearing course of asphaltic concrete (0/14)<br />

between 6 and 8cm thick.<br />

Japanese consortium goes into action<br />

with 16 modern SUPER pavers<br />

For their section of the motorway, the Japanese contractors<br />

are using 12 modern VÖGELE SUPER 2100-2 pavers, each<br />

equipped with the AB 600-2 TP2 Extending Screed,<br />

as well as four SUPER 1900-2 pavers with AB 500-2 TP2<br />

Extending Screeds. The “dash 2” generation machines<br />

certainly have their hands full on the 365km job site. The<br />

VÖGELE pavers are building the three lanes in each direction<br />

in a width of 6.25m, hot to hot. For grade and slope control<br />

with NIVELTRONIC Plus ® , the Japanese teams use the<br />

VÖGELE RoadScan ® sensor system.

Compaction with tandem and rubber-tyred HAMM rollers<br />

Thanks to the ultra-modern VÖGELE machine technology,<br />

the paving teams from Japan are making fast progress,<br />

right on schedule, on their section of the motorway. A fleet<br />

of HAMM rollers is being used for final compaction of the<br />

individual layers. The fleet includes eight 12-ton HD 120<br />

tandem rollers and eight 18-ton GRW 18 rubber-tyred<br />

rollers, capable of reliably producing the specified final<br />

density.<br />

Paving in 12.5m width<br />

The Chinese consortium, too, opted for SUPER 2100-2<br />

pavers to build their section of the motorway. They moved<br />

to the job site with 13 machines. In contrast to the Japanese<br />

teams, the Chinese crews are paving in full-road width.<br />

They built up the screeds of their SUPER 2100-2 machines<br />

to a remarkable pave width of 12.5m. Each of these pavers is<br />

combined with a SB 250 Fixed-Width Screed in TP1 version<br />

for high compaction.<br />

WIRTGEN SP 150, SP 250 and SP 500 Slipform Pavers<br />

The supplementary construction work along the motorway,<br />

such as hard shoulders, is being handled by three<br />

SUPER 1300-2 pavers from the VÖGELE compact equipment<br />

class. Unlike the Japanese, the Chinese paving teams are<br />

using NIVELTRONIC Plus ® , the System for Automated Grade<br />

and Slope Control, in combination with the VÖGELE<br />

Big MultiPlex Ski. When working with this Ski, three sonic<br />

sensors attached to a beam scan an area of up to 13m. Just<br />

like the RoadScan ® System, the Big MultiPlex Ski is highly<br />

flexible and perfectly suited for levelling out all kinds of<br />

irregularities in the base. This is a vital advantage on the job<br />

site in Algeria: even without tensioned wires, the specified<br />

grade and slope is achieved with high accuracy.<br />

SUPER 2100-2 on the scene in major projects<br />

the world over<br />

There are good reasons why road building contractors rely<br />

on SUPER 2100-2 pavers from VÖGELE for so many major<br />

projects. The machine concept of this ultra-modern paver<br />

is designed so that it can handle even the largest road building<br />

Algerian contractors also involved in mega-project<br />

The Algerian contractors moved to the job site around<br />

the capital city of Algiers with two SUPER 1800-2 and two<br />

SUPER 1800-1 pavers. All four VÖGELE machines are also<br />

equipped with High Compaction Screeds. In order to meet<br />

the tight deadline, the paving teams of the Algerian contractors<br />

are using their pavers in 14 hour shifts.


The ultimate in VÖGELE technology on the scene: The Chinese consortium builds its motorway section in full-road width of 12.5m.<br />

VÖGELE partner providing on-site service<br />

On a project like this, not only the job site logistics need<br />

to be strictly organized, but also the supply of spares and<br />

the performance of maintenance services on all machines<br />

involved. The VÖGELE partner for Sales and After-Sales<br />

Services in Algeria, Demdistral S. p. A., handled this work<br />

for the VÖGELE pavers. Mr Ying Erqiang, Deputy Managing<br />

Director of the Chinese construction consortium, was<br />

enthusiastic about the global on-site support: “As far as the<br />

machine technology is concerned, WIRTGEN China provided<br />

us with their expert advice beforehand, and Demdistral is<br />

responsible for the After-Sales Services in Algeria. The<br />

guarantee that the machines will be supplied with parts on<br />

the job site and the reliability of the SUPER pavers are<br />

extremely important factors for us when it comes to meeting<br />

our contractual obligations. I can say that the After-Sales<br />

Service provided by VÖGELE in Algeria is outstanding.”<br />

Representatives of the Japanese and Algerian contractors,<br />

too, confirmed the highly professional service offered by<br />

VÖGELE’s Algerian partner. ,<br />

The world’s largest road construction project currently underway<br />

is realized in North Africa. The 3,200km long motorway “Autoroute<br />

Transmaghrébine” is being built in the three states of Morocco,<br />

Algeria and Tunisia, known as the Maghreb region (in Arabic:<br />

the West), as well as in Libya. Construction of the longest section,<br />

the one running through Algeria and extending over 1,200km,<br />

began in March 2007 and is scheduled to be completed in 2009.<br />

The economic importance of this major project is tremendous.<br />

According to the National Road Agency, the road building<br />

project has created some 100,000 new jobs in Algeria alone,<br />

with the number of jobs created indirectly expected to reach two<br />

to three times that figure.<br />

The motorway passes 55 cities with a total population of more<br />

than 50 million, 22 international airports, as well as the largest<br />

ports, railway stations, universities, hospitals and the most<br />

important industrial and tourist areas in the three Maghreb<br />

states. The “Autoroute Transmaghrébine” thus represents<br />

the most crucial economic nerve of the rising region.<br />

The motorway with three lanes in each direction spans the<br />

country from East to West, passing over 190 bridges and<br />

through five tunnels. After completion, the travel time from<br />

the Tunisian-Libyan border to Morocco will be a mere ten<br />

hours.<br />

The two countries of Libya and Mauritania, both also<br />

members of the Union of the Arab Maghreb (UAM), are<br />

likewise involved in the mammoth project. In the medium<br />
