Performance Evaluation of Rubber Asphalt and Desulfurized Rubber Asphalt
The waste crumb rubber (CR) has been utilized to improve asphalt performance but it shows poor compatibility with matrix asphalt. The approaches of desulfurization and degradation of rubber are proposed to solve the above difficulties. The modified asphalts were prepared with using crumb rubber and desulfurized rubber as modifiers, and matrix asphalt was taken as control group to evaluate the physical properties, high-temperature rutting resistance and low-temperature crack resistance of three asphalts. The results show that both CR and DCR contribute to the positive modification to matrix asphalt, CR modified asphalt exhibits excellent high-temperature rutting resistance and low-temperature cracking resistance. The desulfurization of crumb rubber improves compatibility in asphalt due to the declined molecular weight, thereby enhancing the low-temperature performance of asphalt.
