精表处技术在沥青面层养护维修中的应用

Application of Fine-surfacing Technology in Maintenance of Asphalt Surface

为快速恢复沥青路面使用性能,采用精表处技术对病害进行养护维修,对养护效果进行检验。根据路面使用状况调查和等级评定结果,制定路面病害养护方案。对比分析养护前后路面抗滑性能和渗水系数检测结果,得出路面摆值、构造深度和渗水系数都有一定幅度的改善,满足设计要求,达到了预期效果。

Using the fine-surfacing technology to maintain and repair the disease of the asphalt pavement to rapidly restore the performance, the maintenance effect is tested. According to the investigation and the rating of the pavement condition, a maintenance scheme for the pavement disease is developed. By comparing and analyzing the test results of the pavement skid resistance and water seepage coefficient before and after the maintenance, it can be concluded that the pavement pendulum value, structure depth and water seepage coefficient are improved to a certain extent, which meets the design requirements and achieves the expected effect.
