Abstract: In order to solve the problems of large energy consumption, heavy pollution, poor performance of traditional hot mix asphalt mixture construction and fast cooling and difficult compaction of thin layer overlay, this paper summarizes the performance of warm mix agent, warm mix asphalt mixture and the compaction characteristics of thin layer overlay of warm mix asphalt mixture, and prospects the application of warm mix asphalt mixture on thin layer overlay.

Keywords: warm mix asphalt; thin layer cover; performance characteristics; compaction characteristics
