Improvement of the Low-Temperature Cracking and Shear Resistance of Semi-Flexible Mixture Modified by Polymers

Semi-flexible mixture, as a rigid and flexible pavement material, has good rutting resistance water stability, but its low-temperature cracking shear are poor. This paper studies characterizes the of semi-flexible mixtures modified by redispersible emulsion powder epoxy resin. The performance matrix asphalt mixture cement grouting material with different polymer contents were investigated. flexural polymer-modified measured based on bending test direct test. results indicate that addition polymers, especially resin, can significantly improve failure strain, strength, stiffness modulus strength thus enhancing resistance.
