摘　　要：针对沥青路面抗滑性能的影响因素,从沥青混合料设计的角度,分析了不同类型的集料和混合料级配对路面抗滑性能指标BPN和DF_(60)的影响,分析了OGFC-13沥青混合料的抗滑性能及其衰减规律。研究结果表明:(1)沥青混合料的纹理特征、干湿状态对其抗滑性能影响显著;(2)为保证沥青路面的抗滑性能,应优先选取耐磨性较好的集料,沥青混合料级配类型选取骨架密实结构;(3)OGFC-13沥青混合料类型路表抗滑性能表现良好,能够有效提高行车的安全性能。In response to the factors influencing the anti-slip performance of asphalt pavement,from the perspective of asphalt mixture design,the influence of different types of aggregates and mixture grades on the anti-slip performance indicators BPN and DF60 of the pavement is analyzed,and the anti-slip performance and attenuation law of OGFC-13 asphalt mixture are analyzed.The research results show that:(1) the texture characteristics and dry and wet state of asphalt mixtures have a significant impact on their anti-slip performance;(2) in orderto ensure the anti-slip performance of asphalt pavement,priority should be given to selecting aggregates with good wear resistance,and the grading type of asphalt mixture should be selected as skeleton dense structure;(3) the road surface of OGFC-13 asphalt mixture type has good anti-slip performance,which can effectively improve the safety performance of driving.
