Construction method of highway asphalt pavement by adopting tire initial pressing process
The invention relates to a construction method of a highway asphalt pavement by adopting a tire initial pressing process. The method comprises the following steps that A, an adopted asphalt mixture comprises coarse aggregate, fine aggregate and asphalt, and the particle size of coarse aggregated rock in the coarse aggregate corresponds to the thickness of the asphalt pavement after construction; and B, a pneumatic tyred roller is adopted for initial pressing, that is, a paver paves the asphalt mixture on the roadbed, and the pneumatic tyred roller rolls after following the paver. After initialpressing is completed 2-3 times in a reciprocating manner, a steel cylinder road roller is adopted for final pressing. The top surfaces of the coarse aggregated rock directly form a road surface, andgaps between the adjacent coarse aggregated rock are filled with the fine aggregate. In the highway use process, the top surface of the coarse aggregated rock is directly rubbed with vehicle tires, and the aggregated rock hardness is far higher than that of the tires, so that the pavement is durable and wear-resistant; and meanwhile, the coarse aggregated rock is fixed on the hard roadbed and does not have a space for moving up and down, so that the compaction force and the bearing capacity of the whole pavement are relatively high and are far higher than those of an asphalt pavement in the prior art.
本发明涉及一种采用轮胎初压工艺的公路沥青路面的施工方法，其包括：A、采用的沥青混合料包括粗集料、细集料与沥青，其中，粗集料中的粗石料粒径与沥青路面施工完成后的厚度对应；B、采用轮胎压路机进行初压，即：摊铺机摊铺沥青混合料在路基上，轮胎压路机紧跟摊铺机后进行碾压。往复完成初压2‑3次后，采用钢筒压路机进行终压。粗石料顶面直接构成路面，细集料充填在相邻粗石料之间的间隙中。公路使用过程中，由于粗石料顶面直接与车辆轮胎进行摩擦，石料硬度远高于轮胎，故而路面经久耐磨；同时粗石料被固定在坚硬的路基上，粗石料没有上下位移的空间，故而整个路面压实力、承载力较高，远高于现有技术的沥青路面。
