    1. ASPHA – MINWARM 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 1995 1999 2001 2006 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).
