摘要 文章对比分析了南宁至友谊关高速公路沥青路面采用不同预防性养护措施路段与未预防性养护路段的路况指标、路面结构强度及路面使用寿命,发现AC-8型超薄磨耗层预防性养护措施效果最为理想、值得推广;通过对南宁至友谊关高速公路20处典型路面进行结构强度分析和疲劳寿命验算,发现路面疲劳寿命主要取决于上水稳基层;提出了南宁至友谊关高速公路沥青路面中长期养护建议。 This article compared and analyzed the road condition indicators, pavement structure strength and pavement service life of road sections using the different preventive maintenance meas- ures and road sections without any preventive maintenance of Nanning-Youyiguan Expressway asphalt pavement.It is found that AC-8 ultra-thin wear-layer preventive maintenance measures has the most ideal effect and is worth promoting;through the structural strength analysis and fatigue life checking on 20 typical pavements of Nanning-Youyiguan Expressway, it is found that the fatigue life of pavement mainly depends on upper water-stabilized base,it also proposed the medium and long-term maintenance recommendations for Nanning-Youyiguan Expressway asphalt pavements.
