CRCP Forensic Investigations and Remedial Actions in Virginia

TRB 2010 CRCP Forensics in VAThe key to attaining a long lasting, safe, and economical Continuously Reinforced Concrete Pavement (CRCP) or any other pavement is learning from its performance. Pavement performance is dependent on the characteristics of the materials, the pavement design, and the construction practice used. Therefore, it makes good sense to trace the impact of these elements to identify issues and then to develop a plan of action leading to a high-performing CRCP. Virginia’s plan of action was formulated using all the available talent in several areas, including pavement design, materials selection and testing, research, and the construction practices. The close cooperation with the concrete industry was essential for success. The collective effort resulted in a better understanding of the failure mechanisms, good performance and the interaction among the several factors involved in constructing long lasting CRCP with minimal maintenance. This paper highlights forensic investigations and lessons learned from CRCP projects in the past and how the findings are applied to recently constructed CRCP pavements.
