Project Level Management Decisions in Construction and Rehabilitation of Flexible Pavements

During the pavement life cycle, construction and rehabilitation activities and vehicle-road interactions provoke extensive environmental, economic, and social impacts. Therefore, decision-making systems are developed to derive optimal construction and rehabilitation plans, alleviate the environmental and economic burdens, and simultaneously increase the social benefits. The past studies have developed management systems with different management approaches, optimization tools, objectives, constraints, prediction models, performance indicators, evaluation techniques, evaluation boundaries, and risk paradigms. This study presents and discusses their diverse perceptions and methodologies for these management system elements. Besides the drawbacks in the adopted perceptions, the study presents the further investigations required to develop more efficient systems that optimally achieve the environmental, economic, and social objectives. The review is limited to studies of the international journals undertaken in the past 20 years, which conferred the project-level management of construction and rehabilitation of flexible pavements.
