As part of its strong commitment to designing more environmentally friendly road infrastructure,
Eurovia pioneered the development of so-called warm mixes, which have limited energy impact,
in Europe as far back as 2003. Eurovia’s Tempera® product range includes a new process:
Evotherm® DAT5.
Evotherm® DAT5 was developed by the U.S. MeadWestvaco company, a world leader in asphalt
emulsifiers. Eurovia began applying the process in 2007 as exclusive supplier in a number of
European countries.

3. SOUGHT-AFTER
QUALITies
Evotherm DAT5, a truly versatile process,
®
can be used with most asphalt mixes on road
infrastructure ranging from busy motorways to
roads with low traffic.
Breakthrough
INNOVATION
The Evotherm® DAT5 process constitutes a
new generation of asphalt mixes achieving
temperature reductions of up to 50°C.
The process ensures asphalt mixes of excellent
quality, equivalent to those using conventional
techniques.
Used in the fied of foam bitumen technologies,
more than its temperature lowering power, the
Evotherm® DAT5 additive is a bonding agent which
gives the aggregate similar if not better properties
than traditional hot coated aggregates.
HIGHLY LIMITED
environmental impact
Thanks to its innovative chemistry, the
Evotherm® DAT5 process reduces emissions and
energy requirements. This environmental performance
is achieved without compromising the quality of the
mixes produced.
Highly FLEXIBLE
PRODUCTION
Aqueous concentrated additive solution
Evotherm® DAT5 is injected into the
binder producing then an additivated
foam. The injection system is designed
to fit any continuous or batch mixing
plant without the need to modify
existing equipment.
In addition, the Evotherm® DAT5 process
in no way hinders the operation of the
conventional mixing plant, which can
alternate production of warm and hot
mixes.

4. guaranted SATISFACTION
The formulation of asphalt mixes produced with
the Evotherm® DAT5 process is identical to that
of conventional asphalt mixes; most types of
production are therefore possible.
The performance of the mixes has been confirmed in
core sample campaigns:

Tempera® range, the Evotherm® DAT5 process allows
for recycling through introduction of RAP in the
formula produced, thus helping to conserve nonrenewable resources.
The Evotherm® DAT5 process is protected by numerous patents.
