Study on Performance of Mixed Epoxy Asphalt Mixture

Abstract

In order to get the economic epoxy asphalt (EA) with good pavement performance, mix some Thermoplastic matrix asphalt in different types and mass ratio in the domestic-made epoxy asphalt, then carry on the mix design of the mixed material mixture, and calculate the optimum asphalt-aggregate ratio. The performance of mixture was analyzed by Marshall test, split test, low-temperature bend test, and wheel tracking test. The results show that the basic mechanical performance of MEA mixture still meets the requirements technology standard of EA mixture and MEA mixture has excellent tensile strength, water stability and high temperature stability, and its deformation and low temperature crack resistance performance were strengthened.
