抗滑雾封层技术在公路养护中的应用

Application of Anti-slip Fog Seal Technology in Highway Maintenance

为研究抗滑雾封层技术在公路养护中的应用,文中以某公路为依托,采用玄武岩细集料和高黏沥青两种材料进行雾封层施工,并依据规范验收标准对施工前后路面技术状况进行检测。实践证明,抗滑雾封层施工后路面摩擦系数提升了约10%,构造深度提升了约40%,而渗水系数基本保持不变,表明抗滑雾封层可有效提升路面抗滑性能。

In order to study the application of anti-slip fog seal technology in highway maintenance,this paper uses basalt fine aggregate and high viscosity asphalt for fog seal construction based on a highway,and tests the technical condition of the pavement before and after construction according to the standard acceptance standards.The practice shows that the friction coefficient and the structural depth of the road surface increase by about 10%and 40%after the construction of the anti-skid fog seal,while the water seepage coefficient basically remains unchanged,indicating that the anti-skid fog seal can significantly improve the anti-skid performance of the road surface.
