Abstract: A new type of cold recycled asphalt mixture-Waterborne Epoxy Resin modified emulsified asphalt cold recycled asphalt mixture was proposed and it is the first to use epoxy emulsified asphalt in cold recycled asphalt mixture. The mix design test and the performance verification of the AC-20 cold recycled asphalt mixture of 90% and 70% RAP( Reclaimed Asphalt Pavement) content were conducted by adding the epoxy resin of 0%,10%,20% and 30% modified asphalt emulsion. The results show that the epoxy resin of proper dosage modified emulsified asphalt cold recycled asphalt mixture can have better performance and RAP effective utilization can be further improved.
