摘　　要：随着路龄增长和交通荷载增加,高速公路路面抗滑性能不足问题愈加凸显,通过分析路面抗滑性能影响因素和统计分析大量高速公路现场检测数据、交通等级、路面结构等信息,对不同混合料类型、不同交通等级、不同车道以及不同养护措施的路面抗滑性能开展研究,研究结果表明:交通量越大、货车比例越高,路面抗滑性能衰减越快;高速公路各车道之间的路面抗滑性能存在明显的差异性,第一车道SFC衰减速率低于第二车道和第三车道;与AK-13和PAC-13路面相比,SMA-13路面的抗滑性能和保持效果较好;不同养护措施实施后,按路面抗滑性能衰减速率排序为就地热再生>薄层罩面>超薄磨耗层>普通罩面;从经济效益来看,按PVC值排序为普通罩面>就地热再生>薄层罩面>微表处>超薄磨耗层,超薄磨耗层的经济效益最佳;对于抗滑性能不足且路面破损和车辙病害相对严重的路段,可采用薄层罩面、就地热再生等养护措施;对于抗滑性能不足且伴有轻微车辙病害的路段,可采用超薄磨耗层、薄层罩面养护措施;对于仅存在抗滑性能不足问题的路段,可采用超薄磨耗层、微表处养护措施。With the increase of road age and traffic load,the problem of insufficient skid resistant performance of highway pavement has become increasingly prominent.By analyzing the affecting factors of skid resistant performance of pavement and statistically analyzing a large amount of on-site inspection data,traffic levels,pavement structures of highways,research is conducted on the skid resistant performance of pavement with different types of mixtures,traffic levels,lanes,and maintenance measures.The research results indicate that the larger the traffic volume and the higher the proportion of trucks,the faster the skid resistant performance of the pavement deteriorates;There are significant differences in the skid resistant performance of the pavement between each lane of the expressway,namely the SFC attenuation rate of the first lane is lower than that of the second and third lanes;Compared with AK-13 and PAC-13 pavements,SMA-13 pavement maintains better skid resistant performance and keeps better;After different maintenance measures,according to the degradation rate of pavement skid resistant performance,the order is in-situ thermal regeneration>thin layer overlay>ultra-thin wear layer>ordinary overlay.In terms of economic benefits,according to the PVC value,the order is ordinary overlay>in-situ thermal regeneration>thin layer overlay>micro surface>ultra-thin wear layer,and the economic benefits of ultra-thin wear layer are the best;For road sections with insufficient skid resistant performance and relatively severe road surface damage and rutting diseases,maintenance techniques such as thin layer overlay and in-situ thermal regeneration can be adopted.For road sections with insufficient skid resistant performance and slight rutting defects,ultra-thin wear layer and thin layer overlay maintenance techniques can be adopted.For road sections with insufficient skid resistant performance,ultra-thin wear layer and micro surface maintenance measures can be adopted.
