基于等效面积法的沥青路面预防性养护措施效果评价

本文基于安徽省高速公路路面历史性能数据,采用多元线性回归模型建立了预防性养护措施路面性能发展模型,评价了各预防性养护措施的适用性。针对实际情况采用"等效面积法"评价路面养护效益,考虑到预防性养护措施寿命较短,本文提出二次养护效益费用比的概念,对典型的预防性养护措施的实施效果进行了评价,并对影响养护效益的因素进行了分析。

Effectiveness Evaluation of Asphalt Pavement Preventive Maintenance Measures Based on Equivalent Area Method

Based on historical performance data of highways in Anhui Province,this paper uses a multiple linear regression model to establish a pavement performance development model and evaluates the applicability of each preventive maintenance measure.According to the actual situation,the"equivalent area method"is used to evaluate the pavement maintenance benefits.In view of the short life of preventive maintenance measures,this paper proposes the concept of secondary maintenance benefit cost ratio,and evaluates the implementation effect of typical preventive maintenance measures.The factors affecting the conservation benefits were analyzed.
