摘要
路表抗滑能力对行车安全的影响较大,通过在路表铺设高耐磨抗滑表层可有效提高路面抗滑能力。通过开展室内缩尺加速磨光与老化试验等,评估高抗滑路表抗滑性能与磨光行为,并与未铺设抗滑薄层的普通路表进行对比。研究结果表明,高抗滑路表在磨光和老化过程中的抗滑性能均优于普通路表,且具有较高的抗拉强度,与混合料基面黏结牢固,服役期间不易发生滑移与脱层等层间黏结失效的破坏现象。
The anti-skid ability of road surface has a great influence on driving safety.The anti-skid ability of road surface can be effectively improved by laying high wear resistance and anti-skid surface on the road.The anti-skid ability and grinding behavior of high anti-skid road surface were evaluated by indoor scale accelerated grinding and aging tests,and compared with the ordinary road surface without anti-skid thin layer.The research results show that the anti-skid performance of high anti-skid road surface is better than that of ordinary road surface in the process of grinding and aging,and it has high tensile strength.The high anti-slide road surface is firmly bonded to the base surface of the mixture,and it is not easy to occur the adhesion failure such as slip and delamination during service.
