Asphalt concrete pavement construction method
The application relates to the field of pavement construction, and particularly discloses an asphalt concrete pavement construction method. The asphalt concrete pavement construction method comprisesthe following steps: (1), cleaning a roadbed; (2), laying a cushion layer; (3), laying a middle layer; (4), paving an asphalt mixture to form a pavement layer; and (5), rolling the pavement layer to obtain the asphalt concrete pavement. The asphalt mixture comprises the following components, by mass: 15-20 parts of asphalt, 70-90 parts of coarse aggregate, 10-15 parts of fine aggregate, 3-10 partsof polymer fibers, 1-2 parts of a silane coupling agent, and 1-1.5 parts of polycaprolactam powder. The method has the advantage that the anti-rutting performance of the asphalt concrete pavement obtained through construction is higher.
本申请涉及路面施工领域，具体公开了一种沥青混凝土路面施工方法。沥青混凝土路面施工方法包括以下步骤：步骤（1），清理路基；步骤（2），铺设垫层；步骤（3），铺设中间层；步骤（4），铺设沥青混合料以形成路面层；步骤（5），碾压路面层，即得沥青混凝土路面；沥青混合料包括以下质量份数的组分：沥青15‑20份；粗集料70‑90份；细集料10‑15份；聚合物纤维3‑10份；硅烷偶联剂1‑2份；聚己内酰胺粉1‑1.5份。其具有使得施工所得的沥青混凝土路面的抗车辙性能更强的优点。
