Study on Durability of Granulated Crumb Rubber Asphalt Pavement Based on TPS High-Viscosity Asphalt

Abstract:

In order to improve the durability of granulated crumb rubber asphalt pavement, different amount of TPS modifier are added into granulated crumb rubber asphalt mixture to do tests of water-boiling, water immersion, immersing Marshall, cantabro immersion and some other indoor experiments. Through comparing with base asphalt and SBS modified asphalt, we found that the adhesion ability of asphalt and mineral aggregate and crumb rubber were granulated after adding TPS modifier. The water stability of granulated crumb rubber asphalt mixture is improved. The durability of granulated crumb rubber asphalt mixture has also been improved dramatically. In additions, the optimum mixing volume of TPS for granulated crumb rubber asphalt mixture is 12%; the mixing temperature of asphalt mixture is 185°C.
