LTPP Data Analysis: Consequences of Deferred Treatment of Pavement Preservation Treatment Placement on Asphalt Concrete, Portland Cement Concrete and Composite Pavement Structures

Pavement preservation represents a proactive approach to maintaining and extending the lives of existing highways. A pavement preservation program consists primarily of three components: preventive maintenance, minor rehabilitation (non-structural), and some routine maintenance activities. Within the pavement community, it is widely believed that pavement preservation applications are an effective approach to extending a pavement’s service life. Given the current economic environment, most state departments of transportation (DOTs) are now embracing the pavement preservation philosophy to utilize more cost-effective techniques to better serve the public. However, the consequences of deferred pavement treatment have become an increasing issue in debates over allocation of dwindling budgets for pavement related transportation infrastructure. National Cooperative Highway Research Program (NCHRP) Project 14-38, “Guide for Timing of Asphalt-Surfaced Pavement Preservation,” initiated in 2016, focuses on using a cost-benefit approach to determine the best timing of pavement preservation treatments on asphalt surface pavements, but it will not examine portland cement concrete (PCC) preservation treatments, and it will not look at global optimization issues from the viewpoint of a constrained resource network. The objective of this research is to provide a tool to practitioners on the consequences of deferred corrective treatments on Asphalt Concrete (AC), PCC, and AC over PCC composite pavement structures (i.e., beyond the scope of NCHRP Project 14-38). Asset managers have a responsibility to the public to provide service in a cost-effective manner, and we are now in the age of performance management that requires measuring and reporting performance of the National Highway System. This work includes impacts on vehicle operating costs, sustainable cost accounting, life cycle accounting, and life cycle cost accounting regimens.
