Potential of project level construction and rehabilitation plans to attenuate the economic and environmental burdens of flexible road pavements: A review study

During the life cycle of road pavements, transportation agencies spend large funds for maintenance and rehabilitation. Additionally, vehicle operating costs and fuel consumption are extremely associated with the road pavement condition. Moreover, both rehabilitation actions and commuter usage provoke extensive environmental burdens. Thus, many studies investigated the roles of rehabilitation strategies and management systems in exploiting funds judiciously, attenuating user costs, and alleviating environmental burdens. This study summarizes the main findings of the past studies and provides some perspective reviews for compromising the economic and environmental appurtenances provoked during the road pavement life cycle. It is revealed that the management system, rehabilitation strategies, and case context have intertwined and intensive impacts on the provoked economic and environmental burdens. The review is limited to studies published in international journals over the last 20 years. The study fosters only those studies that considered the whole life cycle at the project level.
