Abstract

The accumulation of waste tires will lead to "black pollution", posing environmental problems. In order to use effectively the waste tire rubber, solve the technical problems about using the waste tire rubber as a material additive, tests were conducted on asphalt mixtures of four types (AH-70, CR7, CR10 and CR13) made from waste tire rubber, in AC-13 aggregate gradation. The physical and rheological characteristics are analyzed through the Marshall experiment, rutting test, splitting test, bending test at low temperatures for the four types of the asphalt mixture. The analyses include the effects of rubber power contents on the properties of the asphalt. Test results show that the addition of rubber power would effectively improve the performance and the temperature sensitivity. Compared to AH-70, CR7 and CR13, the rubber modified bitumen CR10 is found to have the most satisfactory pavement performance.
