Research on Epoxy Hot Recycling Performance of Waste Asphalt Mixture
In response to the problems of low waste blending rate and poor road performance of traditional asphalt pavement hot recycling methods,this article conducts research and application of epoxy hot recycling waste asphalt mixture,determines the proportion of epoxy asphalt binder and the mix proportion of hot recycled mixture through indoor experiments,and verifies the various performance indicators of epoxy recycled mixture.The relevant results indicate that the Marshall stability,high-temperature stability,water damage resistance,and water tightness of epoxy recycled mixture are better than those of fresh asphalt mixture,and have good road performance.The epoxy asphalt plant mixed hot recycling technology can achieve a waste utilization rate of 100%,maximize the utilization of waste milling materials,effectively reduce maintenance costs,and significantly improve the high temperature stability and rutting resistance of asphalt pavement.
