(1) Merge and analyze dynamic response data obtained on full-scale pavement facilities for the purpose of determining how various design features and truck configurations affect pavement performance. (2) Use dynamic response data obtained to validate and calibrate a set of truck/pavement predictive analysis models and implement these models in practical problem solutions of pavement design and truck size and weight issues.

Active. Study is almost halfway over. A status meeting with state representatives will occur in March 2002. Trials have been set up and are being followed. The initial kick-off meeting was held in Washington D.C. on February 15, 2000 to establish priorities and a general outline of research tasks. Following the initial meeting, two separate but detailed work plans were generated with study tasks prioritized based on their importance to partners and general funding. The separate work tasks were reviewed and approved by the Technical Panel. Final approval of the work plans was issued on December 13, 2000 to establish January 1, 2001 as the official start date of the study. Since then, ODOT has contracted with Ohio University to perform their approved tasks while the FHWA has issued task orders to conduct much of their approved tasks through in-house staff (on-site contractor staff).
