Research on Decision-making Indicators and Standards for Comprehensive Maintenance of Highway Asphalt Pavement
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.
