This enables mixing and handling temperatures to be reduced by 20 to 55°F (10 to 30°C). During cooling, Sasobit crystallizes and forms a lattice structure in the asphalt increasing the asphalt stability. Sasobit can be blended into hot asphalt at the mixing plant using a simple stirring device. A high-shear mixer is not required.

Sasobit (a synthetic hard wax). Each clip by weight, contains 50% wax and 50% fiber; with a wax melting point of 216F (101C). The wax application gives the fiber the needed weight to adequately be distributed into the mixing drum. As the Sasobit wax melts, it allows the dry fibers to disperse evenly into the asphalt and aggregate mix.
