Environment protection in application of asphalt mixture

In order to control the emission volume of CO₂ in the production of asphalt mixture for pavement, this paper introduced the application of medium-sized temperature technology in asphalt mixture, and the application and research of normal temperature asphalt mixture in Japan and Finland, analyzed the technique of cold-temperature asphalt mixture and cold-recycled asphalt mixture used in China, studied the environment protection in the construction of asphalt mixture pavement. It was pointed that using the medium-sized temperature technology can decrease the mixing temperature of asphalt mixture, its compaction degree is not decreased, so the emission of CO₂ can be reduced.
