Continuous Deflection Testing of Texas Pavements
To assess the structural condition and bearing capacity of existing or newly constructed pavement systems, the most commonly used nondestructive testing device is the Falling Weight Deflectometer. The Falling Weight Deflectometer is a stop-and-go (discrete testing) operation, which increases testing time and operational cost and creates an unsafe working environment due to traffic interruptions. To measure deflection profiles at or near highway speeds, various national and international research efforts have taken place in the last decade. However, the status, reliability, operational speed and cost, and limitations of the developed systems are unknown. The objectives of this research project were to summarize the state-of-the-art of continuous deflection measurement systems and identify a suitable device that meets Texas DOT criteria.
