Is an outstanding asphalt modification product that is designed for use in asphalt that must be able to meet special requirements and large loads over a longer period of time. This was developed in recognition of the fact that standard bitumen has limited mechanical properties.
As Ventraco developed this product, it was important that it should be feasible to add the product in a standard batch mixer without any or with only a few adjustments. In addition, a regular asphalt team should, with only minimal directions, be able to work with the modified asphalt.
WKR-2, the very latest generation of the WKR products, consists of a mixture of EVA, waxes and antioxidants. It is still the only modification that is based on a mixture of polymers, and that can be added batch-wise.
The only modification which contains a mixture of polymers
Rapid dispersion in the asphalt mix
Also contains antioxidants and adhesion promoters
Extreme adhesion on the aggregate, for enhanced durability
Both automatic and batch dosing is feasible
Can be reused in ordinary asphalt
