摘要
沥青路面表层抗滑能力的大小对行车安全问题起决定性的作用。非人为因素下,抗滑性能不足的路面通常不能在规定时间内使移动的车辆及时制动,往往出现滑移或者制动距离过长,从而造成交通事故。结合横向力系数测试车在广东仁博高速公路LM5合同段的应用,通过在不同路段的SMA-13沥青路面全天连续测试,分析温度对横向力系数SFC值的影响。
The anti-skid ability of the asphalt pavement surface plays a decisive role in driving safety.Under non-human factors,the moving vehiclescannot brake in time on the pavement with insufficient anti-skid performance,where often slipping or braking distance is too long,thus causing traffic accidents.Being combined with the application of sideway force coefficient test vehicle in LM5 contract section of Renbo Expressway in Guangdong Province,in this paper,the influence of temperature on sideway force coefficient SFC value has been analyzed through continuous testing of SMA-13 asphalt pavement in different sections throughout the day.
