摘要
为提高彩色沥青路面色彩耐久性并研究其抗滑性能,采用有机硅-聚丙酸酯(silane-modified polyacrylate,SMP)对彩色沥青玛蹄脂碎石混合料(color stone mastic asphalt,CSMA)和彩色开级配抗滑表层(color open graded friction course,COGFC)2种混合料改性,借助小型加速加载设备进行对彩色沥青路面进行色彩耐久性评价,并通过三维扫描仪进行路面纹理信息采集,分析路面三维参数与其抗滑性能之间的关系。结果表明,SMP改性剂可有效提高CSMA、COGFC两种混合料的抗磨耗能力,提升彩色沥青色彩耐久性;CSMA及COGFC路面抗滑性能受到不同三维参数的影响,路面的摩擦系数模型由各自相关因子控制,增加路面暴露的集料数量和使用尖角集料能使彩色沥青路面的抗滑性能得到提升。
In order to improve the color durability of colored asphalt pavement and study its anti-slip performance,silane-modified polyacrylate(SMP) was used to modify the two mixtures of color stone mastic asphalt(CSMA) and color open graded friction course(COGFC).The color durability of colored asphalt pavement was evaluated with the help of small accelerated loading equipment,and the pavement texture information was collected by 3D scanner to explore the relationship between the three-dimensional parameters of the pavement and its anti-slip performance.The results show that SMP modifier can effectively enhance the wear resistance of CSMA and COGFC and improve the color durability of two colored asphalt.The anti-slip performance of CSMA pavement and COGFC pavement is affected by different three-dimensional parameters,and the friction coefficient model of pavement is controlled by their respective correlation factors.The anti-slip performance of colored asphalt pavement can be improved by increasing the number of aggregates exposed to pavement and using sharp aggregates.
