| Summary: | In order to study the effects of Sasobit on rubber asphalt, performance tests of rubber asphalt before and after Sasobit adding and tests of different Sasobit adding processes were operated. The influences of Sasobit on the performance of rubber asphalt, effects of Sasobit adding process on Sasobit rubber asphalt were acquired. The results showed that: Sasobit makes the high temperature viscosity and low temperature ductility of rubber asphalt decrease, and the softening point increase, which are favourable to the workability and high temperature stability, and disadvantageous to the low temperature ductility of rubber asphalt; the preparation process of Sasobit rubber asphalt by adding Sasobit into the finished rubber asphalt is better.
