水泥路面加铺罩面适应性分析

Analysis on Applicability of Cement Pavement Overlay

该文通过收集三条国道干线公路菏泽市城区段水泥路面加铺罩面实体工程建设资料,从原路面使用状况着手,开展了交通量及轴载状况调查;从加铺罩面材料选择、结构层厚度与组合、抗裂效果等方面分析了加铺罩面工程在相应道路上的适应性。研究表明,三条公路加铺罩面工程,反射裂缝防治效果良好,路面行驶质量及抗滑性能优良,能很好地适应道路使用要求。

According to the construction data collected from the cement pavement overlay projects of three national highways in the town section of Heze City,the article introduces the investigations of traffic flow and axle load condition,and analyzes the applicability of overlay engineering in the relative roads from three aspects,i.e.the selection of overlay materials,the thickness and combination of structural layer,and the anti-cracking effect.The study shows that the reflecting crack preventive effects of three highway overlay projects are good,and the driving quality and anti-slip performance are excellent able to better adapt the road requirements.
