摘　　要：为了提升超薄罩面的抗滑性能,采用MMLS3加速加载测试方法,对比研究了OGFC-10及2种OGFC-7车辙板在经过不同加载次数后的构造深度、摩擦系数及分形维数的变化情况。结果显示:1)OGFC-10的初始抗滑系数略大于OGFC-7,但OGFC-7的抗滑性能衰减度更小,且可通过添加高黏剂的方式进一步提升其抗滑性能及其耐久性。2)OGFC-7粒径更小,更适宜用于超薄罩面,可作为道路养护维修中抗滑超薄罩面。In order to improve the slip resistance performance of the ultra-thin cover,MMLS 3 accelerated loading test method was used to compare the construction depth,friction coefficient and fractal dimension of OGFC-10 and two OGFC-7 rut plates after different loading times.The results show that the initial slip resistance coefficient of OGFC-10 was slightly greater than that of OGFC-7,but the slip resistance performance decay of OGFC-7 was smaller,and its slip resistance performance and durability can be further improved by adding high viscosity agent.In addition,combined with the characteristics of OGFC-7 with smaller particle size and more suitable for ultra-thin cover,OGFC-7 can be used as a new idea of slip resistance ultra-thin cover in road maintenance.
