The majority of the Washington State Department of Transportation (WSDOT) portland cement concrete (PCC) pavements have far exceeded their original design lives and have carried several times the traffic loading originally anticipated. WSDOT is undertaking a major effort to identify both rehabilitation and reconstruction projects to improve its PCC pavements.
This project was performed to estimate WSDOT’s concrete pavement performance. The current PCC pavement conditions were thoroughly analyzed. Two major groups of concrete pavement deterioration models were systematically studied: HDM-4 and NCHRP 1-37A. NCHRP 1-37A models proved to be more suitable for WSDOT conditions. The calibrated faulting and roughness models are able to present the typical performance of WSDOT PCC pavements. These models can be used to assist WSDOT in developing a plan for rehabilitating or reconstructing these pavements.
