Asphalt concrete pavement construction method
The invention relates to an asphalt concrete pavement construction method, and the method comprises the following construction steps: S100, defining a roadbed construction range, excavating and compacting a roadbed, and uniformly paving gravels on the surface layer of the roadbed to form a lower bearing layer for later use; S200, preparing a densely-matched asphalt mixture on site, uniformly paving the asphalt mixture on the surface layer of the roadbed, and compacting the asphalt mixture for several times; S300, performing the joint cutting on the constructed half roadbed in batches, whereinthe joint cutting width needs to be greater than 200 mm, and the joint cutting width must be perpendicular to the bottom; S400, covering the surface layer of the roadbed with non-woven geotextile to preserve moisture and maintain health, and performing traffic control; S500, after curing is finished, performing coring on the surface layer of the roadbed at certain intervals, performing a strengthtest on a coring sample, and checking and accepting the coring sample used for traffic after the general standard is met. The invention has the effects that the forming time of the asphalt concrete pavement is shortened, and normal traffic of the road is effectively guaranteed.
本申请涉及一种沥青混凝土路面施工方法，其包括如下施工步骤：S100、圈定路基施工范围，开挖路基并压实，在路基表层均匀摊铺碎石以形成下承层，以备用；S200、现场制备密集配型沥青混合料，均匀摊铺在路基表层后分次压实；S300、分批次对已施工的半幅路基进行切缝，切缝宽度需大于200mm，且必须垂直到底；S400、在路基表层覆盖无纺土工布以保湿养生，并进行交通管制；S500、养生结束后，在路基表层间隔一定距离取芯，对取芯样本进行强度试验，符合通用标准后验收并通车使用。本申请具有缩短沥青混凝土路面的成型时间，有效保障道路正常通车的效果。
