Abstract: Compared with the traditional hot mix asphalt mixture, the mixing and compaction temperature is relatively low. At the same time, the hot mix asphalt reduces energy consumption and exhaust emissions, and has good road performance. So the warm mix asphalt is a new type of energy saving and environmental friendly road material. There are some problems encountered in the development and application of warm mix asphalt. In order to promote the application of warm mix asphalt mixture and realize the sustainable development of the industry, this study analyzes the warm mix asphalt mixture principle and status quo based on summing up the characteristics of warm mix asphalt mixture on, and analyzed the existing warm mix asphalt mixture in question.
