重载交通桥面沥青铺装抗剥落性能的影响因素研究

Study on influencing factors of anti-spalling performance of asphalt pavement for heavy-duty traffic bridge deck

文章采用实验室模拟实验的方法对沥青铺装抗剥离性能的影响因素及影响力大小进行研究。研究发现:沥青的种类、沥青的用量、集料的种类以及粒级配伍均是剥落性能的显著影响因素。研究结论:环氧沥青的抗剥落特性最好,集料选择玄武岩,并在粒径为级配中值最为适宜,能够极大地发挥抗剥离属性。

In this paper, the method of laboratory simulation experiment is used to study the influencing factors and influence of the anti-stripping performance of asphalt pavement. The research found that the type of asphalt, the amount of asphalt, the type of aggregate and the compatibility of particle size are all significant factors that affect the spalling performance. Research conclusion:epoxy asphalt has the best anti-stripping properties, and the aggregate is selected from basalt, and the particle size is the most suitable for the median value of the gradation, which can greatly exert the anti-stripping properties.
