IME-TESTED
EFFectiveness
Viaself® Fv is a range of asphalt mixes that can be
laid at temperatures ranging from their production
temperature to ambient temperature.
Viaself® Fv can be conventionally laid by machine,
and it is also especially suitable for reprofiling edges
and for emergency repairs of damage such as
potholes, trench reinstatement, footpath repairs, etc.
Each type of mix within the range has been
designed and formulated to achieve workability and
appearance similar to those of conventional hot
mixes.
Laying can be deferred and the material can be
stored ready to use for up to 2 months. Viaself® Fv is
made in a special production process, in continuous
or batch mixing plants, at a temperature of 40 to
120°C.
The excellent workability of Viaself® Fv provides very
broad flexibility of use. It can be laid by paver or
grader as well as manually. Compaction equipment is
identical to that used for hot and warm mixes.
Note that this range of mixes has been frequently
employed by Eurovia Brittany in projects carried out on
islands off the coast, with the mix manufactured on the
mainland.

4. OPTIMISed
FORMULations
Viaself® Fv is made of a 0/4, 0/6, 0/10 or 0/14 densegraded aggregate skeleton coated with a specially
formulated fluxed bitumen.
The binder employed to produce Viaself®Cé Fv is a
70/100 or 160/220 bitumen plastified through the
addition of an agro-chemical oil. Unlike petrochemical
or petroleum oils, this plant-based oil does not
evaporate but hardens in place, on the pavement,
through oxidation in air.
The bitumen with plant-based fluxing agent used in
Viaself® Fv is produced by a special process in Eurovia
binder plants. It was designed to achieve coating
viscosity at low temperature that is close to that of
pure bitumens used in conventional hot bituminous
material processes. This coating binder complies with
the NF EN 15322 standard.
A comprehensive range of fluxed asphalt mixes has
been developed by optimizing the nature and plantbased fluxing agent content of the products. Fluxing
agent content, and hence binder type, is selected
according to laying conditions.
The Viaself® Fv range covers several products suitable
for a variety of applications:
iaself® C Fv for surface courses,
V
iaself® R Fv for reprofiling,
V
iaself® S Fv for one-off repairs.

Plant-based oils were selected for their fluxing
capacity and their ability to oxidise after laying so as to
achieve more or less rapid cohesion depending on the
application.
