1. Paving method construction asphalt pavement surface layer Paving method construction asphalt pavement surface layer has two types: asphalt surface treatment and asphalt infiltration. Asphalt pavement is a thin pavement pavement with a thickness less than 3cm, which is usually constructed by layered method. According to the number of layers of paving asphalt and mineral aggregate, it can be divided into three types: single-layer, double-layer and triple-layer, and single-layer and double-layer are part of the triple-layer. The construction technology of the three-layer surfacing is as follows: clean the base, and before the surfacing construction, clean the pavement base to expose most of the mineral materials at the base and keep it dry; If the overall strength of the foundation is insufficient, it should be strengthened first. Spread asphalt on the top layer (or adhesive layer). Spread asphalt evenly on the first layer. If there is any blank or missing edge after paving asphalt, it should be filled with asphalt immediately. If there is any accumulation, it should be scraped off immediately. During construction, asphalt distributor should be used to spray asphalt, and its distribution length should be coordinated with the distribution capacity of mineral aggregate. The asphalt spreading temperature shall be determined according to the construction temperature and asphalt label. In general, petroleum asphalt should be 130℃ ~ 170℃, coal asphalt should be 80℃ ~ 120℃, and emulsified asphalt should be spread at room temperature.
