改性乳化沥青在微表处预防性养护中的应用

Application of Modified Emulsified Asphalt in Preventive Curing of Microsurface

文中以某高速公路为例,对该道路病害类型及分布特点,提出微表处施工技术方案,将改性乳化沥青、集料等材料按比例拌制,所产生的混合料用于下层、上层、雾封稳固层各部位的微表处施工。实践证明,微表处经施工后,路面损坏状况得到缓解,路面的抗滑性能、平整性均有所提升,路面使用状态良好。

In this paper,taking a highway as an example,the type and distribution characteristics of the road disease,put forward the micro surface construction technology scheme,the modified emulsified asphalt,aggregate and other materials in proportion to mix,the resulting mix used in the lower,upper,fog seal stable layer of each part of the micro surface construction.Practice has proved that:after the construction of the micro-surface,the damage condition of the pavement has been alleviated,the anti-skid performance and smoothness of the pavement have been improved,and the pavement is in good condition.
