Technical Standards of Rubber Asphalt and Crumb Rubber Modified Asphalt

Abstract:

Rubber asphalt and crumb rubber modified asphalt are the internationally recognized best way to disposal of waste tires, harmless treatment and resource utilization. The applications of rubber asphalt and asphalt mixture with scrap tire rubber powder in the highway construction are in the ascendant and the relevant standards are the precondition of the application. In order to fit the needs of the development form, SINOPEC and Research Institute of Highway in the Ministry of Communications put forward their own standards, but with different definitions of waste crumb rubber modified road asphalt and obvious different technical standards, etc. So, in this paper according to the introduction and comparison of these two standards to further standardize the technical index of the scrap tire rubber powder, selection, production process, production process and technical index of rubber asphalt and crumb rubber modified asphalt and the material selection and the design process of mixture; the technical reference and support to the extensive application can be also got.
