超薄沥青罩面加铺层路用性能检测评价

Detecting Evaluation of Road Performance of Ultra-thin Asphalt Overlay

超薄沥青罩面层开裂是导致罩面层各项路用性能下降的根源,为了准确评价沥青罩面层当前的工作状况,必须进行相应的性能检测;以山西省内某省道路面养护处治施工标段为背景,重点分析了罩面层平整度、抗滑性及抗冻性3项路用性能指标的检测方法及评价结果。检测结果表明,该养护标段的3项路用性能指标均达到规范要求,路用性能总体良好。

The fundamental reason for the degradation of pavement performance of the overlay is the cracking of the ultra-thin asphalt overlay.In order to accurately evaluate the current working conditions of the asphalt overlay,corresponding properties detection must be carried out.Based on the pavement maintenance and treatment construction section of a provincial highway in Shanxi Province,this paper focused on analyzing the detection methods and results of three road performance indexes,which are overlay evenness,slip resistance and frost resistance.The results show that,the three road performance indexes of this maintenance section all meet the specification requirement and the overall road performance is good.
