综述国内外有关沥青混凝土路面预防性养护时机确定的方法,指出单指标界定模型的不合理性;结合目前国内技术规范中路面性能评价指标,提出了针对预防性养护的路面综合评定模型;利用综合评定模型和实测数据借助EXCEL宏形成云南省典型高速公路沥青混凝土路面的衰变曲线三级模型,提出沥青混凝土路面预防性养护时机的衰变曲线拐点理论,并结合单指标预防性养护区间验证了拐点理论应用的正确性。
This paper summarizes the domestic and international methods for determining the timing of preventive maintenance of asphalt concrete pavement and points out the irrationality of the single index in defining the model. Based on the evaluation index of the pavement performance in the current domestic technical specifications, a comprehensive pavement evaluation model for preventive maintenance is proposed. Evaluation Model and Measured Data Based on the three-level model of decay curves of asphalt concrete pavement of Yunnan Province, the inflection point theory of decay curve of preventive maintenance timing of asphalt concrete pavement was proposed by using EXCEL macro, and the inflection point theory was verified with the single-index preventive maintenance interval The correctness of the application.
