抗滑表处封层技术在新台高速公路路面的应用

随着路面表层使用年限的增加,路面病害也逐步增多,其中尤以裂缝与坑槽病害显得较为严重。为了改善沥青路面的使用性能,防止路面病害的加速发展,保障行车安全,不仅要对已形成的裂缝与坑槽病害进行修补外,还应对路面表层进行适当养护。以新台高速公路为例,采用抗滑表处封层技术对表层路面性能进行修复养护,并对施工后三个时间段的表观质量、渗水系数、平整度、抗滑性能(横向力系数与构造深度)等指标进行了跟踪检测,结果表明路面结构的整体性能均得到了较大程度的改善。

Application of Anti-sliding Surface Sealing Technology in Pavement of Xintai Expressway

With increasing of overlay service life,the number of pavement diseases also increases,especially the diseases of cracks and potholes become much more serious.In order to improve the performance of asphalt pavement,prevent the accelerated development and expansion of pavement diseases,and ensure traffic safety,cracks and potholes shall be repaired in time.Taking Xintai Expressway as an example,in this paper,by using anti-slide surface sealing technology to repair the pavement diseases,the apparent quality,permeability coefficient,flatness and anti-slide performance(transverse force coefficient and structure depth)of the three time periods after construction have been monitored.The results have shown that the overall performance of pavement structure has been greatly improved.The research results could provide some references for similar projects.
