摘要:本文介绍了沥青路面预防性养护雾涂层技术,以及该技术在沿江高速公路上应用研究的简要情况。通过检测喷洒前后路面不同时间的抗滑值、构造深度、渗水系数、平整度以及不同施工层数、不同配比的效果等来研究其路用性能,并得出了初步结论。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,但不会影响路面的摩擦性能,而且其防水效果较好,施工过程也比较简单、快速。

Abstract::This paper introduces the technology of Fog Seal for Asphalt Pavement Preventive Maintenance(PPM) ,and the application on Yanjiang Expressway. Some performance indexes of pavement such as Friction coefficient、Texture depth、Infiltration coefficient、Pavement evenness and the effects of different ratio or seal 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 function, it will conspicuous enhance the waterproof effect, and its constructing technology is simple and rapid.

预防性养护(PPM)实质上是一种周期性的强制保养措施,它并不考虑路面是否已经有了某种损坏。因此预防性养护最佳实施时机应该是在路面尚处于良好状况[1]下进行,它能防止路面
