specificity
A specific product
Exclusively dedicated to karting race courses,
Viafirst® Kart fits all types of race courses, to
both indoor and outdoor, for new construction or
maintenance.
For this type of carrying out, a special importance
is granted to the driver’s experience considered
as one of the criteria of work acceptance. As the
evenness is therefore an important component
of success, laying of Viafirst® Kart imperatively
requires a binder course and a suitable guidance
mode.
A
n adapted result
Viafirst® Kart is a thin asphaltic concrete 0/10mm
or 0/6mm continuous graded type C as defined by
the standard EN 13108-1. It is preferably used
with a modified bitumen, from the Styrelf® or
Polybitume® range. These bitumens show a strong
cohesion, a weak thermal susceptibility, a great
elasticity and an excellent aging resistance.
Exclusively used as a surface layer, it is laid with
a thickness of minimum 40mm (in the case of
0/10mm) or 30mm (0/6mm). A tack coat with
emulsion, of about 350g/m2 of residual bitumen,
is always associated with Viafirst® Kart. It
contributes to the waterproofing of the pavement
structure and to a good bonding of the layers.
By a systematic laboratory mix design,
Viafirst® Kart allows to obtain surface
characteristics adapted to the client’s request.

4. A
ll characteristics
of a specific solution
The mix design of Viafirst® Kart leads to an asphalt
concrete flexible but resistant that shows by the
way good surface characteristics.
Gyratory Shear Press - GSP (EN 12697-31)
Void content at 40 gyrations
5% ≤ GSP ≤ 9%
Water sensitivity (EN 12697-12, method A)
ITSR

Rutting (EN 12697-22)
Rutting depth on a 5cm thick slab,
at 60°C and 30,000 cycles
Subject to the validation by a mix design study,
Viafirst® Kart can be produced according to the
warm mix processes of the Tempera® range.
It authorizes recycling by adding reclaimed asphalt
pavement in the produced formula contributing to
the preservation of natural resources and to energy
savings.
Furthermore, producing with warm mix processes
simplifies considerably the working conditions,
when the laying of Viafirst® Kart has to be carried
out inside .
