Practical Smoothness Solutions with ProVAL

George K. Chang, Transtec Group, Inc., presiding

Sponsored by Committee on Surface Properties – Vehicle Interaction (AFD90); Committee on Characteristics of Asphalt-Aggregate Combinations to Meet Surface Requirements (AFK40); Committee on Weigh-in-Motion (ABJ35(2)); Committee on Highway Traffic Monitoring (ABJ35)

ProVAL is essential for project-level construction acceptance and network-level tests (e.g., the Highway Performance Management System). Featured in this hands-on workshop are practical solutions for automated smoothness analysis with exclusions, smoothness assurance module, and optimal weigh-in-motion site locator (OWL). OWL implements AASHTO Standard MP14-11 to qualify existing WIM sites and select new WIM sites; therefore, it is critical to ensuring quality traffic input to DARWIN-ME.
