Highway asphalt pavement anti-skid treatment process
The invention relates to an anti-skid treatment process for a highway asphalt pavement, which relates to the technical field of road construction and comprises the following steps: S1, uniformly brushing a layer of primer on the paved asphalt pavement to obtain a primer layer; s2, spreading a layer of glass beads on the primer layer before the primer layer is cured; s3, uniformly mixing the primer, a matting agent and water according to a mass ratio of 1: (0.5-0.8): (12.5-18.5) to obtain a top coating, and uniformly spraying the top coating on the primer layer; s4, carrying out curing and drying treatment on the asphalt pavement; the primer is a two-component waterborne polyurethane coating, and the viscosity of the primer is 350 to 600 mPa * s. The two-component waterborne polyurethane coating is paved on the asphalt pavement and matched with the glass beads, so that the wear resistance of the asphalt pavement can be further improved, the skid resistance of the asphalt pavement is further improved, and the asphalt pavement has good weather resistance and mechanical strength.
本申请涉及一种公路沥青路面抗滑处理工艺，涉及道路施工技术的领域，包括以下步骤：S1.在铺设完成的沥青路面上均匀刷涂一层底涂料得到底涂层；S2.在所述底涂料固化前在底涂层上撒布一层玻璃微珠；S3.将所述底涂料、消光剂以及水以1:(0.5‑0.8):(12.5‑18.5)的质量比混合均匀后得到面涂料，将所述面涂料均匀喷洒于底涂层上；S4.对沥青路面进行养生和干燥处理；所述底涂料为双组分水性聚氨酯涂料，所述底涂料的粘度为350‑600mPa·s。本申请通过在沥青路面上铺设双组分水性聚氨酯涂料并搭配以玻璃微珠，可以进一步提升沥青路面的耐磨性能，进而提升沥青路面的抗滑性能，并具有良好的耐候性和机械强度。
