Asphalt highway construction method
The invention discloses an asphalt highway construction method, which comprises the following steps of: 1, leveling a roadbed, namely filling sand and gravel materials in hollow positions on the roadbed, and leveling and compacting the roadbed by using a leveling machine; The method has the beneficial effects that through rapid laying of the base layer and the asphalt surface layer, the watering curing process of the base layer is omitted, the base layer is converted from bare artificial curing to closed curing after covering of the asphalt surface, curing conditions are more favorable, the curing period of the base layer is canceled and shortened, and the construction efficiency of the asphalt road is greatly improved. Meanwhile, the change amplitude of the water content in the base layer is small, the defect that the change amplitude of the water content of the base layer is large due to manual curing is overcome, and reduction and avoiding of shrinkage cracks caused by the change of the water content of the base layer are facilitated; and furthermore, the asphalt surface layer and the base layer are compressed and formed through inosculating after fast laying. The pushing deformation between the asphalt surface layer and the base layer when the asphalt road is used after construction is effectively avoided, and the service life of the asphalt road is prolonged.
本发明公开了一种沥青公路施工方法，步骤1：路基整平：在路基上的坑洼位置填补砂砾料，并采用整平机上对路基进行整平压实。有益效果在于：本发明通过基层与沥青面层的快速铺设，不仅省去了基层的洒水养生过程，使得基层由裸露人工养生转变为覆盖沥青面后的封闭养生，养生条件更为有利，取消和缩短了基层养生期，极大的提高了沥青公路的施工效率，同时基层内的含水量变化幅度较小，避免了人工养生所带来的基层含水量变化幅度较大的弊端，对减少以及避免因基层水分变化而产生的干缩裂缝更为有利，而且快速铺设后沥青面层与基层通过嵌合后压实成型，有效避免了沥青公路在施工后使用时沥青面层与基层之间的推移变形，提高沥青公路的使用寿命。
