乳化沥青雾封层技术是一种常用的预防性养护技术,但目前乳化沥青雾封层没有形成统一的性能评价方法和标准,较大程度上依赖于乳化沥青的评价体系。本文对乳化沥青评价体系在雾封层技术方面的适用性进行了分析,提出了适合于雾封层的乳化沥青残留物回收方法,并自行设计试验方法对乳化沥青雾封层材料进行了路用性能评价。 Emulsified asphalt seal technology is a commonly used preventive maintenance technology, but the current emulsified asphalt seal does not form a unified performance evaluation methods and standards, largely depends on the emulsified asphalt evaluation system. In this paper, the applicability of emulsified asphalt evaluation system in fog seal technology was analyzed, and the method of recovering emulsified asphalt residue suitable for fog seal layer was put forward. The test method was also designed to apply the emulsified asphalt fog seal material Performance evaluation.
