基于路面功能的雾封层养护措施效果评价

在广东省惠河高速公路上的一些试验段采取了三种雾封层预防性养护措施,根据2004年至2006年间各个时期试验段路面功能检测的结果,进行数理统计后绘制成图表,并引入变化率,采用多重比较的方法对三种雾封层的养护措施效果进行科学评价。结果表明,无论哪种雾封层措施,实施后均会降低原路面的抗滑性能和渗水系数,但不会使抗滑性能降低到现行规范要求值以下;如果使用得当,可以延长路面寿命,延缓修复的时间。上述的数据分析方法适用于预防性养护措施的效果评价。

Evaluation of Conservation Measures for Road Surface Feature Layer of Fog Seal

Three types of preventive conservation measures on fog seal have been taken on the Huihe highway of Guangdong province. Based on the testing period on the function of road surface feature from the year of 2004 to 2006, we have conducted a series of figures, and put in the change rate as well. What＇ s more, we have made several different ways of comparison to evaluate the three types of conservation measures. The result indicates that, whatever kind of measure it is, it will induce the cling property and seepage coefficient of the surface, but it will not make the cling property down under specification requires. If it is conducted properly, it can lengthen the life of the road surface and defer the repairing time. The data above can be used as the evaluation of contingency conservation measures.
