1 ASPHA – MIN WARM ASPHALT MIXES A Division of Eurovia

2 Eurovia / MHI Originators of Zeolite Warm Mix Technology

3 History Development starts at MHI Earliest trial sites on public roads in Germany (Hesse and Thuringia) Start of an international corporation with EUROVIA; numerous sites in Europe and North America since then Start of the distribution company aspha-min GmbH, Hanau (Germany)

4 Product Info [aspha-min ® ]; synthetically manufactured zeolite (containing approx. 20 % water of crystallisation by mass) allowing the manufacture of warm mixed asphalt © 2007 aspha-min GmbH, Hanau (Germany).

5 Product Info Impact of aspha-min ® : Added to the mix shortly before or at the same time as the binder at a rate of 0.3% by mass, the zeolite starts to release water, creating a very fine water spray This controlled foaming effect leads to a slight increase of the binder volume The gradual release of the water provides the impact over a longer period of time (6 to 7 hrs.) The effect lasts until the mix has cooled to (212° F) thus ensuring comfortable workability of the mix © 2007 aspha-min GmbH, Hanau (Germany).

6 Product Info Benefits of aspha-min ® in WMA: Compatible with all currently used types of binder Compatible with all currently used types of mix Compatible with the use of RAP No change to the ball-and-pen value Easy handling and dosing Stable storage when kept dry No additional storage facilities for pre-mixed binder No major modifications to the plant No prolongation of the mixing time © 2007 aspha-min GmbH, Hanau (Germany).
