Pavement Maintenance and Management

This chapter reviews the fundamental theory and methods of pavement maintenance and management. It covers the concept and development of pavement management systems, the main approaches to pavement condition survey and evaluation, and the principal maintenance and rehabilitation strategies for flexible and rigid pavements. Representative indices and testing methods, including IRI, FWD, and TSD, are introduced to illustrate the technical basis of pavement performance assessment. The chapter also discusses life cycle cost analysis and life cycle assessment as important tools for evaluating maintenance alternatives from economic and environmental perspectives. The content provides a comprehensive framework for linking pavement condition assessment with maintenance decision-making and sustainable pavement management practice.
