摘　　要：针对水泥乳化沥青混凝土(CAC)抗滑性不足的问题,参考水泥混凝土路面抗滑构造方法,提出了碎石撒布、表面刷毛、水泥乳化沥青碎石抗滑层3种提高抗滑性的方法;综合分析表面构造深度及摆式摩擦系数,优选出合理的表面抗滑构造方式,并研究了其耐磨性及抗滑衰减规律。结果表明,水泥乳化沥青碎石抗滑层,可以有效提高水泥乳化沥青混凝土的抗滑性能,是最优的处治方式。Aiming at insufficient skid resistance of cement-emulsified asphalt concrete (CAC) and referring to the skid resistance texture of cement concrete pavement,three methods of improving skid resistance are proposed which are gravel spreading,surface texturing and anti-skid layer of cement emulsified asphalt macadam.Based on comprehensive analysis of the depth of surface structure and the coefficient of friction,a reasonable surface anti-skid mode is selected and its wear resistance and anti-skid attenuation law are studied.The results show that the anti-skid layer is the best treatment method which can effectively improve the skid resistance of cement emulsified asphalt concrete.
