Taking into account the nature of their binder, the usual asphalt concretes do not resist well to the contact with hydrocarbon and petroleum products. There were successful studies in order to improve the performance of bitumen regarding these aggressive agents. Kérovia® is an asphalt concrete based on a modified binder with the most common gradings 0/10 or 0/14 mm elaborated by Eurovia for surfacings subject to accidental spillage of petroleum products. Kérovia® is laid to a thickness of between 40 and 90 mm.

3. a new
reference
The fuel resistance has been appreciated for years by
the Duriez test after immersion into diesel or kerosene.
With the implementation of the European standards,
a new test subject to standard NF EN 12697-43 allows
to quantify differently this performance.
In summary, this standard is divided into two phases:
- phase A, a density loss, after steeping in the fuel of
the upper 35 mm, of test specimen (the selected fuel
- diesel or kerosene - risks of coming into contact with
the asphalt concrete according to the project),
- phase B, a second density loss after washing
with water, mechanical drying and brushing of the
immerged surface.
These two phases simulate first of all the initial loss
due to accidental spillage of fuel on the road, then
afterwards degrading over time through traffic stress.
This decomposition in two test phases seems to
be more realistic of the phenomenon on the road
compared with the immersions carried out before.

4. a well directed
study
The nature of the aggregates and special requirements
of the client can sometimes lead Eurovia to
incorporate additives in the Kérovia® formula in order
to make it more resistant to every surfacing stress.
There is not great experience on the new test, but
it is already undeniable that the performance with
the binder used, when steeping or brushing, could be
different, as the comparative tests carried out by the
company’s research center show:

These tests showed among other things an influence
of the aggregates’ origin composing the asphalt
concrete. That is why Eurovia will select the adequate
bitumen within its range of modified cross-linked
bitumen according to the selected aggregates and the
final destination of the project to be carried out.
In any case the Kérovia® binder is a modified bitumen
with a microstructure that optimizes the asphalt
concrete performance regarding the hydrocarbon
spillages.

Commentary
A WIDE RANGE
of use
The kerosene resistant character of Kérovia® makes
it quality surfacing especially for surfaces subject to
risks of accidental spills of petroleum products: airport
areas with traffic and aircraft parking spaces, industrial
parking and heavy vehicles, military equipment fields,
bus floors, etc.
In case of intensive and continuous chemical stress,
it is advisable to use a surface course in cement
concrete, in paving stone or to plan surface protection
application.
Eurovia offers in its range of special products other
solutions that also have good hydrocarbon resistance.
