沥青路面抗滑性能影响因素识别研究进展

沥青路面作为公路建设的重要内容,其抗滑性能是道路安全问题的核心,探究其影响因素可以为提高路面抗滑性能提供依据。国内外学者对此做了大量研究,也取得了相应的进展。本文对国内外的研究成果进行了系统的归纳总结,将公路沥青路面抗滑性能影响因素分为了沥青混合料的材料特性、环境因素、车辆特性3个主要方面,其中在沥青混合料的材料特性方面,研究认为集料的结构特性与混合料配合比对抗滑性的影响较大;环境因素方面,研究认为温度对于抗滑性的影响较大;车辆特性对抗滑性的影响方面,研究认为主要体现在轮胎特性与荷载方面。此外随着行车速度的增加,路面的抗滑性能呈现降低趋势。

Research Progress on Identification of Factors Influencing skid Resistance of Asphalt Pavement

Asphalt pavement as an important part of highway construction,its anti-sliding performance is the core of road safety issues,to explore its influencing factors can provide basis for improving the skid resistance performance of pavement.Scholars at home and abroad have done a lot of research and made corresponding progress.In this paper,the research results at home and abroad are systematically summarized,and the influencing factors of highway asphalt pavement anti sliding performance are divided into three main aspects:material characteristics of asphalt mixture,environmental factors and vehicle characteristics.In the aspect of material characteristics of asphalt mixture,the research considers that the structural characteristics of aggregate and the anti-sliding performance of mixture ratio have a greater impact;environmental factors The results show that the temperature has a great influence on the skid resistance;the influence of vehicle characteristics on the skid resistance is mainly reflected in the tire characteristics and load.In addition,with the increase of driving speed,the skid resistance performance of pavement shows a decreasing trend.
