Rheofalt® LT-70 

Rheofalt® LT-70 is a special synthetic paraffin wax formulation that also contains antioxidants. It reduces bitumen viscosity and improves the processability of the asphalt mixture. 

The asphalt temperature can be reduced by up to 70°C. This means that Rheofalt® LT-70 offers a 30 to 40°C improved temperature reduction than other ordinary waxes. Due to the reduced temperature of the asphalt mixture, longer transport distances are possible. RheoFalt® LT-70 also increases the stability of the asphalt pavement.
