针对目前雾封层预养护技术没有统一的评价指标和评价方法的现状,在对比分析现有研究基础上,推荐了基于工艺性能、使用性能和耐久性能要求的雾封层养护材料评价体系。其中的耐久性评价,室内试验推荐采用加重磨耗试验,可以评价雾封层的养护效果;现场试验采用改进的耐磨性试验,可以评价路面性能,预估雾封层的使用寿命;对浙江某地区2012年~2015年采用雾封层养护的5.9km桥面进行现场试验,证明该方法可以评价预防性养护材料耐久性。
In view of the fact that there is no uniform evaluation index and evaluation method for the pre-curing technology of fog seal, based on the comparative analysis of the existing research, the evaluation system of fog seal material based on process performance, service performance and durability performance is recommended. One of the durability evaluation, laboratory tests recommended to increase the wear test, the evaluation of the effect of the fog seal conservation; field test using an improved wear resistance test, you can evaluate the performance of the road to predict the life of the fog seal layer; a Zhejiang In the field from 2012 to 2015, a field test of 5.9km decks covered with fog seal was conducted to prove that this method can evaluate the durability of preventive maintenance materials.
