摘　　要：In this paper, the research on warm mix asphalt construction technology of asphalt surface course in low temperature season in cold areas is carried out. The research project is guided by surface theory, mortar theory, strength theory and asphalt concrete regulations, based on solid engineering practice, aiming at breaking through the bottleneck of Asphalt Mixture Construction under low temperature environment, through repeated tests and optimization. Carry out a series of studies including the selection of warm mix agent, the formula, road performance and construction technology of warm mix asphalt mixture, and start from four aspects: the selection of warm mix agent, the proportion and technology of warm mix asphalt mixture, the road performance of warm mix asphalt mixture and the construction technology of warm mix asphalt mixture expressway. It has formed a complete set of technical scheme and control standard system for selecting and determining the optimal type and dosage of warm mix agent, reasonable raw material ratio, mixing process and parameters, road performance and applicability of warm mix asphalt mixture, and construction of warm mix asphalt process in low temperature season of asphalt pavement engineering.
