Construction method of highway asphalt pavement
ActiveCN102011360AIncreased durabilityPrevent intrusionIn situ pavingsRoads maintainenceEngineeringRoad surface
The invention relates to a construction method of a highway asphalt pavement with long service life, which is suitable for ensuring highway quality. The construction method comprises the following steps: carrying out initial rolling by using a tyre roller: the tyre roller rolls 2-3 times after a spreading machine, and the temperature of the pavement is 120-150 DEG C in the rolling process; and finishing final rolling by using the steel roller. In order to prevent the material from attaching to the tyres, the temperature of the pavement is kept above 100 DEG C when the tyre roller is used for finishing initial rolling. Since the temperature of the pavement during initial rolling is high and the kneading amplitude of the tyres is high, the weight of the tyre roller can be properly reduced, and the design requirement for pavement compactness can be satisfied only by rolling 2-3 times. The rolling quality of the pavement is determined by temperature. Asphalt in the materials can easily form a thick seal oil film layer on the pavement, thereby preventing the invasion of water, mud and air, being beneficial to preventing the pavement from being damaged by water and enhancing the durability of the pavement.
