摘要
我国现行规范规定了高速公路沥青路面养护需求所需考虑的PSSI、PCI、RQI、SRI和RDI等评价指标,然而路面养护决策不仅受上述指标的影响,而且与路面结构材料、交通轴载及路龄等因素相关,采用主成分分析法确定了路面养护决策所需考虑的关键影响因素及其权重,提出了路面综合养护决策指标及其标准,客观表征了综合多因素的高速公路沥青路面养护需求.
Abstract
The current specifications in China stipulate the evaluation indexes such as PSSI,PCI,RQI,SRI and RDI that should be considered in the maintenance demand of expressway asphalt pavement.However,the decision of pavement maintenance is not only affected by the above indexes,but also related to the factors such as pavement structural materials,traffic axle load and road age.In this paper,the principal component analysis method is used to determine the key factors and their weights that should be considered in the pavement maintenance decision,and the decision indexes and standards of comprehensive pavement maintenance are proposed,which objectively characterizes the maintenance needs of highway asphalt pavement with multiple factors.
