Abstract

In order to realize the sustainable development of transportation infrastructure, more and more attention has been paid to the multi-scheme selection method of road engineering, while the existing life cycle cost analysis (LCCA) and life cycle assessment (LCA) methods are often isolated from each other, which cannot better realize the comprehensive evaluation of road life cycle. This chapter will review and summarize the development of LCCA and LCA systematically. Pointing out the existing problems in current research, the idea of integrated evaluation method combining LCA and LCCA is proposed. It puts forward the future development direction based on the deficiency of the current research results and provides useful reference for the popularization and application of the life cycle methods in road engineering.

Keywords: life cycle assessment, life cycle cost analysis, transportation infrastructure
