沥青路面在我国公路中所占的比例最高,这主要与其较高的路面平整度、良好的力学性能,便于养护维修的特点直接相关。据统计,我国沥青路面在通车里程中远远高于水泥路面,尤其是高速公路。然而,由于种种原因,沥青路面的早期破坏严重,而预防性养护是沥青路面早期破坏处理的有效措施之一。微表处作为预防性养护的一种常见形式,被广泛应用在各级公路中。文章基于微表处技术的预防性养护实践,从微表处
Asphalt pavement has the highest proportion of highway in our country, which is directly related to its high pavement smoothness, good mechanical properties and easy maintenance. According to statistics, the mileage of asphalt pavement in our country is far higher than that of cement pavement, especially the expressway. However, due to various reasons, the early destruction of asphalt pavement is serious, and preventive maintenance is one of the effective measures for early destruction of asphalt pavement. Micro-surfacing is a common form of preventive maintenance and is widely used at all levels of the road. The article is based on the micro-surfacing technology for preventive maintenance practices from micro-surfacing
