Assessment of Survival Probabilities of Continuously Reinforced Concrete Pavements

This paper proposes a theoretically sound method of modeling the reliability function of pavement sections, using a statistical procedure that can correctly consider test sections that have not yet reached failure. Consistent and accurate reliability estimates were obtained applying this method to a continuously reinforced concrete pavements (CRCP) data base where only 12070of the test sections had failed. The reliability calculated with the revised AASHTO model is used to discuss the consequences of using inadequate statistical methods, and the proposed method is offered as a theoretically sound alternative, that can be applied to any pavement data base.
