IMPROVED HOT MIX ASPHALTS CONTAINING RECLAIMED RUBBER

Tests have been carried out to determine the extent of the interaction between asphalt cement and reclaimed rubber from used tires, and also the void content and the Marshall flow and stability of hot mix asphalts made therefrom. In addition the flexural properties of rubber-asphalt concrete slabs have been determined, and sections of road have been laid with these materials. Viscosity measurements suggested that there was very little interaction between reclaimed rubber and asphalt cement at 200 C, whether the rubber were devulcanized or not.
