Study on the storage stability of Centralizing Supply Crumb Rubber Modified Asphalt

In order to improve the restrictions of wet processing on traditional rubber asphalt, the fundamental performance test and storage stability verification of the Centralizing Supply Crumb Rubber Modified Asphalt (CS-RMA), which has a long-term storability and stability performance, were conducted through comparing with the traditional Rubber Modified Asphalt (RMA). The results show that the CS-RMA has a similar fundamental performance to RMA, without the existence of solid core rubber particles. The 22% dosage of the CS-RMA comparing with others dosage has a better workability. In addition, the CSRMA has a more superior performance of segregation resistance as well as a better compatibility and stability performance under high temperature and a long-term static storage.
