Expressway Asphalt Pavement Structure Evaluation Method Frame Based on LCCA

Life Cycle Cost Analysis (LCCA) is an effective tool to contrast pavement structures and achieve high cost-effectiveness ratio of the pavement structure scheme. This paper, based on the consideration that there is little research on expressway asphalt pavement structure evaluation method in China, conducts a tentative study in this field. After an introduction to the research background home and abroad and an analysis of the user cost components of LCCA, the expressway work zone user cost analysis method is proposed firstly at home to replace usual user cost as expressway LCCA method, and a general method frame for expressway asphalt pavement structure evaluation based on LCCA is presented in accordance with the reality in China.
