摘要
采用抗滑性能检测、落锤式弯沉仪模量反算等方法对橡胶沥青超薄磨耗层在试验段的应用效果进行了跟踪观测,结果表明:铺筑超薄磨耗层的路段经过3年使用,抗滑性能比未加铺该层路段高出30%左右,抗滑性能的衰减速度也较慢。另外,该层的铺筑在短期内对路面结构性能影响不大,但在长期使用过程中,可使路面保持较好的强度均匀性,从而大大延缓路面结构破坏的发生。
Rubber asphalt ultra-thin wearing course performance were evaluated on testing road using skid resistance test and FWD modulus back-calculation ect.after three years,the skid resistance was 30% higher than that of pavements without ultra-thin wearing courses,.Besides,although this effect of the wearing course on pavement structural conditions is not significant in short-term,in the long term the wearing course could improve the strength uniformity and slow the structure damage rate.
