微表处设计方法及施工质量研究

Design Method and Construction Quality of Micro Surfacing

微表处技术可延缓沥青路面老化、改善路面抗滑性能和修复路面局部缺陷,在路面养护工程中得到了广泛应用。通过室内试验,对微表处混合料的配合比进行了设计,并结合工程实际,介绍了微表处现场施工工艺流程以及施工控制要点。

The micro surfacing technique can delay the aging of asphalt pavement, improves the skid resistance and repair the local breakage. Therefore it is widely used in pavement maintenance. The mix proportion of micro-surfacing mixture is designed by indoor tests. The construction technique process and control points of in-site micro surfacing are introduces combining with practical engineering experience.
