Paper Title:
Research on Pavement Characteristics of Epoxy Resin and Rubber Modified Asphalt
  Abstract

An asphalt modified by epoxy resin and rubber has the following improved properties: the softening point is 70 , elastic recovery rate is 80%, and kinematic viscosity at 175 is 2879.1mm2 /s. In order to solve the early curing in the process of mixing, storage and transportation, methyl hexahydrophthalic anhydride(MHHPA) was used as the curing agent. A reflective cracking caused by traffic load simulation test was established with the objective to compare the propagation speed of reflective crack of three different structure asphalt mixture samples. The results showed that the sample with epoxy resin and rubber used as stress-absorbing layer can obviously delay reflective cracking, improve the pavement performance and prolong the road life. Furthermore, the results of Marshall test, immersion Marshall test and Rutting test were consistent with the results of the reflective crack simulation test.
