摘要
分别选择通车年限为2年、3年、5年、7年的4车道高速公路各一条,选取代表性路段实测车辙深度,同时通过录像记录车辆经过超车道、行车道横断面位置,统计得到有效宽度、有效宽度位置,分析车辙深度与有效宽度及有效宽度位置的关系,得出随着车辙深度的增加,超车道有效宽度减小幅度小于行车道,行车道有效宽度位置随着车辙增加右移;采用MK6双轮横向力系数测试仪进行抗滑性能检测时的有效范围应为有效宽度减小10cm,对通车7年以上的高速公路进行抗滑性能检测需慎重。
A four-lane expressway with a service life of 2 years, 3 years, 5 years, and 7 years is respectively selected, the measured rut depth on the representative section is selected, and meanwhile the effective width and the effective width position are obtained through the statistics of video recording of the cross section position of the passing lane and the traffic lane, so as to analyze the relationship between the rut depth and the effective width and the effective width position, and draw the conclusion that with the increase of the rut depth, the reduction of the effective width of the passing lane is smaller than that of the traffic lane, and the position of the effective width of the traffic lane moves to the right with the increase of the rut;when the MK6 two-wheel lateral force coefficient tester is used for anti-sliding performance testing, the effective range should be 10 cm less than the effective width, and the anti-sliding performance testing of expressways that have been open to traffic for more than 7 years should be carefully considered.
