In practical application, it has many kinds of properties, such as solid, anti rutting, durability, smoothness, anti slide, anti crack, anti water and cold, and so on. In recent years, with the rapid development of science and technology, many new materials and new technology has been widely used, but due to various factors, there are still many technical problems in the construction, and Gansu Province in the northwest of China, the remoteness of expressway construction technology compared with other developed city is backward, so the part from the highway asphalt concrete pavement the need to strictly control each link. Mainly has the quality of raw materials, the staff of the construction technology of strict requirements, to build a qualified highway. This paper describes the construction of the Gansu highway A3 asphalt concrete pavement materials needed: road asphalt, emulsified asphalt, liquid petroleum asphalt, modified asphalt, modified asphalt, coarse aggregate, fine aggregate, filler, fiber stabilizer, asphalt mixing material and other materials are introduced and the the quality of the ma
