Product info
Product Info

[aspha-min®]; synthetically manufactured zeolite (containing approx. 20 % water of crystallisation by mass) allowing the manufacture of warm mixed asphalt

Product info1
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

Product info2
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
