EvoTHERm® DAT5

tempera® Warm mIX prOduCt range

A breakthrough innovation

evOtherm® dat5mInImum energY, maXImum QuaLItYAs 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.

BreakthrOugh InnOvatIOnThe 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.

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.

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.

hIghLY LImIted envIrOnmentaL ImpaCtThanks 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.

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:

On each worksite, the measured properties are

compliant with the applicable specifications for the

type of asphalt mix laid. Like all asphalt mixes in the

Tempera® range, the Evotherm® DAT5 process allows

for recycling through introduction of RAP in the

formula produced, thus helping to conserve non-

renewable resources.
