Determination of rheological properties of modified asphalt binder incorporating with sasobit additive

This study investigates the rheological properties of bitumen (asphalt) binder penetration grade 80-100 and 60-70 modified with an additive Sasobit wax. This additive is a Long-Chain Aliphatic Hydrocarbon (LCAH). It is obtained from coal gasification using the Fischer-Tropsch process. Bitumen is vis...
