摘要
采用现场试验及理论分析相结合的方法,分析了路面抗滑性能机理,总结综述了沥青路面抗滑性能的影响因素,结合重庆山区多雨特殊地理气候条件,通过重庆地区4条高速公路6年间的横向力系数测试数据,分析了高速公路沥青路面抗滑性能衰减规律,并提出了保持高速公路良好抗滑性能的建议,研究成果可供高速公路沥青路面养护参考。
The mechanism of pavement anti-skid performance is analyzed by means of field test and theoretical analysis.Influencing factors of anti-slide performance of asphalt pavement are summarized.Combined with rainy geographical and climate conditions in Chongqing,the attenuation law of anti-slide performance of asphalt pavement is analyzed through the test data of transverse force of four highways in 6 years in Chongqing.Suggestions to maintain good anti-skid performance are put forward.The research results can be used for asphalt pavement maintenance.
