沥青路面预防性养护雾封层在沿江高速公路上的应用

Application of Fog Seal in Asphalt Pavement Preventive Maintenance On Yanjiang Expressway

通过对检测喷洒前后路面不同时间的抗滑值、构造深度、渗水系数和平整度等路用性能指标研究。分析了预防性养护雾封层在沿江高速公路的应用状况。根据对检测数据分析得出:SUPREME雾封层技术尽管会轻微降低路面的构造深度,但不会影响路面的使用性能,而且防水、防渗效果较好,施工也比较方便。

This paper introduces the technology of fog seal in asphalt pavement preventive maintenance(PPM),and the application on Yanjiang expressway.Some performance indexes of pavement such as friction coefficient,texture depth,permeability coefficient and pavement evenness are measured before and after applying fog seal.The date indicates that although the using of SUPREME fog seal will reduce lightly the texture depth,but it will not influence the using performance,it will improve the waterproof effect,and its constructing technology is easy.
