摘　　要：根据城市副中心慢行系统道路的特征,采用防滑降噪效果良好的UTAC-10超薄罩面。对UTAC-10进行配合比设计,对其路用性能检测及评价分析,并分析了粘层材料的种类和喷洒量及喷洒温度对抗剪切强度的影响,最后对UTAC-10的功能性使用效果评价。结果表明:UTAC的路用性能良好,采用高黏乳化沥青作为粘层材料能满足抗剪强度的要求,超薄罩面服役一段时间后整体状况良好。Based on the characteristics of urban sub center slow moving system roads,UTAC-10 ultra-thin cover with good anti slip and noise reduction effect was adopted.Firstly,the mix design of UTAC-10 was carried out,and its road performance was tested and evaluated for analysis.Secondly,the influence of the type of adhesive layer material,spraying amount and spraying temperature on the shear strength was analyzed.Finally,evaluate the functional use effect of UTAC-10.The results showed that UTAC-10 has good road performance,and using high viscosity emulsified asphalt as the adhesive layer material can meet the require-ments of shear strength.The ultra-thin cover was in good overall condition after serving for a period of time.
