mastic asphalt, asphalt hot mix + grouting asphalt pavements

5.2 Mastic asphalt, asphalt hot mix and
grouting asphalt pavements
Hot mix pavements as wearing surfaces
on FOAMGLAS ® compact insulation
systems are available in various
European countries as an alternative to insitu
concrete wearing slabs, pavements in
a bed of fine gravel or prefabricated slabs/
paving on spacer pads.
The following describes and illustrates the
main asphalt construction systems.
Mastic asphalt,
asphalt hot mix,
grouting asphalt pavements etc.
require a knowledge of materials and systems
which require the employment of
specialist companies.
The description of system solutions given
below does not claim to be complete and
is based on the relevant national regulations.
In general, with systems of this type, the
following factors:
- build-up of heat,
- stability and
- live loads under the effect of temperature
should be considered.
The placing of wearing surfaces and work
on the details is a business that must be
carried out by experts. As a manufacturer
of insulation materials, Pittsburgh Corning
wants to document by a wide selection of
projects its solid experience with the versatile
FOAMGLAS ® insulation products
and systems.

The case studies presented do not cover
all technical details, nor do they have any
validity for future liability claims in the
event of damage or system defects.
Transmission of forces and
choice of insulation
If dynamic forces are transmitted under a
pressure cone of ~45° on concrete load
distribution slabs with a mastic asphalt
wearing surface, the distribution effect for
mastic asphalt, rolled asphalt, asphalt hot
mix and grouting asphalt pavements is
much lower.
This means that greater layer thicknesses,
or else FOAMGLAS ® products with higher
compressive strengths, must be used to
obtain the same stress resistance.
To avoid the need for extra thicknesses of
the wearing course, FOAMGLAS ® types
S3 or F are normally used.
