> Licomont ® BS 100 for bitumen modification<br />
in road construction<br />
Exactly your chemistry.
What can be achieved with Licomont ® BS 100<br />
> Incorporation into the bitumen as well as the mixed mineral<br />
> Protection of wearing parts during production of mixed material<br />
> Energy-saving production of mixed materials; short mixing time<br />
> Improvement of the adhesion of the bitumen on the mineral<br />
> Considerable decrease of transport and paving temperature<br />
> Reduced heat radiation and vapour generation<br />
> High compacting degree during construction (cohesion)<br />
> Good deforming resistance at high temperatures<br />
> Lower tendency to form wheel tracks<br />
> No increased risk of crack formation at low temperatures<br />

Problem: Permanent increase of road loading<br />
> Enormous increase of traffic; especially of<br />
long-distance haulage<br />
> Increase of super-single-tyres on trucks<br />
> High surface pressure<br />
(warehouses, container terminals, permanent increase<br />
of axle pressure, slow driving trucks)<br />
> Highly increase of allowed axle load (today up to 12 tons)<br />
> Permanent increase of allowed laden weight<br />
(today up to 60 tons)<br />
Solution: Modifying of Bitumen respective Asphalt<br />
As was already mentioned, it’s possible to modify the bitumen. The modification gives more hardness to the asphalt<br />
to prevent sinkings in the road. There are basically two types of additives for modifying bitumen:<br />
High molecular (polymers)<br />
> SBS; SBR; SIS<br />
> EVA (e. g. Elvax ® from Dupont)<br />
> Licocene ® /Polymers (Clariant)<br />
Low molecular modification<br />
with Amide wax<br />
(e. g. Licomont ® BS 100 from Clariant)<br />
The new super-single-tires form wider and deeper sinkings<br />
than earlier wire types did.

Influence of Licomont ® BS 100 on the<br />
Hardness of Bitumen<br />
The resulting benefits are:<br />
> Very good coldness-stability – no frost damages<br />
> Excellent deformation resistance at higher temperature<br />
> Avoidance of wheel trucking<br />
> Improvement of processing parameter<br />

Tracking Test with Bitumen 70/100 - 20.000 Overruns at 50 °C<br />
To have not only laboratory results,<br />
a test track was build up. The penetration<br />
depth in modified and nonmodified<br />
Bitumen 70/100 is shown in<br />
this diagram.<br />
But not only the absolute values of the<br />
penetration depth show the positive<br />
effects, also the development of the<br />
penetration compared to the number<br />
of overruns show the outstanding<br />
stabilization of bitumen with Licomont<br />
BS 100.<br />
On balance the result was:<br />
Licomont ® BS 100 should be used in any<br />
cases where high stability and life<br />
span of the asphalt road is especially<br />
important. Without modification<br />
