Measuring Faulting on Jointed Concrete Pavements
On an annual basis, TxDOT collects most of its required distress information through a contracted vendor. However, faulting, one of the essential distresses, is estimated from longitudinal profile data, which is neither reliable nor accurate enough for establishing performance measures. Recent reforms enacted by MAP-21 (Moving Ahead for Progress in the 21st Century Act) include transitioning to a performance-based program, including establishing national performance goals for Federal-aid highway programs. The FAST Act (Fixing America's Surface Transportation Act) continues this performance management approach, within which states invest resources in projects that collectively will make progress toward national goals. The FAST Act shortens the timeframe for states and metropolitan planning organizations to make progress toward meeting performance targets under the National Highway Performance Program and clarifies the significant progress timeline for the Highway Safety Improvement Program performance targets. It is under this framework that the research team will develop a reliable measurement system to identify, measure, and calculate faulting on all jointed concrete pavements (JCP). In particular, this project has the objective of developing a system to collect and verify faulting data of JCP in an accurate manner at highway speeds during daylight conditions. This project will deliver end products to meet a TRL Level 8.
