Development of Jointed Concrete Pavement Database for State of Texas

A jointed concrete pavement database was developed as part of a pavement information management system for Texas. Topics discussed include the identification of variables, a statewide selection of pavement projects using an experimental factorial design, and the collection of performance information through a visual condition survey. A preliminary distress index for jointed pavements is also presented. In this analysis, the distress variables collected in the field are reduced to a single performance value and related statistically to the various design variables of the pavement projects investigated.
