精表处在闻垣高速预防性养护中的应用

Application of precision surface in preventive maintenance of Wenyuan expressway

结合高速公路沥青路面精表处预防性养护案例,探究精表处对沥青路面的养护效果。通过路面状况调查,分析确定精表处养护方案。为了合理评价精表处养护效果,在施工现场布置测点对养护前后的渗水系数、摩擦系数等指标进行检测,分析结果得出养护后沥青路面的使用性能明显提高,养护效果明显。

Combining the case of preventive maintenance of the fine surface of the highway asphalt pavement,explore the maintenance effect of the fine surface on the asphalt pavement.Through the investigation of road conditions,analysis and determination of the maintenance plan of the fine surface.In order to reasonably evaluate the maintenance effect of the fine surface treatment,measuring points were arranged on the construction site to detect the water seepage coefficient and friction coefficient before and after the maintenance.The analysis results show that the service performance of the asphalt pavement after maintenance is significantly improved,and the maintenance effect is obvious.
