The warm mix asphalt technology refers to the asphalt mixture technology which is used to carry out asphalt mixing and operation at a low temperature through certain technical measures and maintain its performance not less than hot asphalt mixture at the same time. The mixing temperature is between hot asphalt mixture (150℃-180℃) and cold (room temperature) asphalt mixture, while the performance reaches (or close to) hot asphalt mixture. This technology is applicable to all grades of highway asphalt pavement and building layer, and its wide application value shows in the areas with high air quality requirements (such as tunnels). In addition, this technology is to make asphalt foamed, expand the volume and significantly decrease the viscosity by adding water, which finishes coating with the aggregate at a low temperature, thereby performing the mixing and operation at a low temperature to reduce pollution emissions. After evaporation of water, asphalt recovers to its original physical properties, with the added water content being about 2% of the asphalt mass.
