摘要
预防性养护雾封层措施是一种简便易行的路面防护措施,但目前对其作用效果的系统评价研究很少。本文通过某高速公路上的试验路实体工程,现场检测了雾封层措施应用前后反映路面功能的各项性能指标,介绍了若干种预防性养护雾封层措施的施工工艺,对各种检测数据进行分析,评价雾封层措施的使用效果。检测数据表明:所评测雾封层措施,尽管会轻微降低路面的抗滑性能,但不会影响路面的使用功能,而且防水、防渗效果明显,施工也比较便利。
The preventive maintenance fog seal is easy and effective for pavement preservation. There is not enough systematic evaluation for the effects of fog seal until now. According to a highway experiment road, some performance indexes of pavement are measured locally before and after applying fog seal. The construction technology of some fog seal treatments is introduced, all kinds of data analyzed, and the effects of fog seal evaluated. The data indicate that although the using of fog seal will reduce lightly the skid resistance, it will not influence the using function, and it will enhance the waterproof effect obviously, its construction technology is easy.
