EVALUATION OF SASOBIT FOR USE IN WARM MIX ASPHALT
of hot mix asphalt without sacrificing the quality of the resulting pavement. One of these processes utilizes Sasobit®, a synthetic long chain Fischer-Tropsch wax. Sasobit® can be blended with the binder at a terminal or in the contractor’s tank, introduced in a molten form, added with the aggregate, or pneumatically blown into a drum plant.

What does Sasobit do to make an asphalt a warm mix? Sasobit lowers the viscosity of the mix and also acts as a flow modifier. While in it’s liquid state, this modification allows the aggregate to move more freely in the binder. When Sasobit cools and crystallizes it forms a uniform network structure in the binder.
Performance of Warm Mix Asphalt containing Sasobit®: State-of ...
In this case, the Sasobit®-WMA mixtures were produced at an asphalt mixing plant and loaded into trucks at 180 °C. The trucks were equipped with heat shields over the top of the asphalt associated with three layers of carpet under felt, as well as the typical tarpaulin covers used to prevent significant asphalt mix loss.

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.
