摘要
在沥青路面上实施雾封层措施后的一段时间内,路面抗滑性能会有一定程度地降低。因此,在实际工程应用中提出了基于HAP路面防护剂的HAP(石屑)封层措施。文中依托试验路工程研究HAP(石屑)封层措施的抗滑性能和防水性能,结果表明该措施能够减少抗滑性能的降低或略微提高抗滑性能,同时可保持雾封层良好的防水性能。
Within a period of time after fog seal on asphalt pavement, skid resistant of pavement will be reduced on a certain extent. Therefore, HAP （chip） seal coat has been put forward based on HAP pavement protecting agent in practical engineering application. This paper studies skid resistance and waterproof performance of pavement with HAP （chip） seal coat based on the experimental section engineering. The result indicates that this measure can reduce degradation of skid resistance or improve skid resistance slightly as well as keep good waterproof performance of fog seal.
