Pavement gravel seal coat and construction method thereof
The invention relates to a pavement gravel seal coat and a construction method thereof. The pavement gravel sealing layer comprises an asphalt gravel layer and a polyurethane gravel layer which are in contact, the asphalt gravel layer is located on the lower layer of the pavement gravel sealing layer, and the asphalt gravel layer is derived from emulsified asphalt and first aggregate; the polyurethane rubble layer is located on the upper layer of the pavement rubble sealing layer, and the polyurethane rubble layer is derived from polyurethane and second aggregate. The pavement gravel sealing layer has excellent temperature stability and durability and high fatigue limit. When the road surface gravel sealing layer is used, the using amount of cementing materials can be reduced, and the rapid traffic passing effect is achieved. The pavement gravel seal coat has excellent abrasion resistance, and the service life of the pavement can be greatly prolonged.
本发明涉及一种路面碎石封层及其施工方法。路面碎石封层包括相接触的沥青碎石层和聚氨酯碎石层，其中，所述沥青碎石层位于所述路面碎石封层的下层，且所述沥青碎石层源自于乳化沥青和第一集料；所述聚氨酯碎石层位于所述路面碎石封层的上层，且所述聚氨酯碎石层源自于聚氨酯和第二集料。本发明的路面碎石封层具有优异的温度稳定性和耐久性，疲劳极限高。使用本发明的路面碎石封层时可降低胶结料用量，并具有快速通车的效果。本发明的路面碎石封层具有优异的抗磨耗性能，可极大提高路面使用寿命。
