Abstract:

This report describes the evaluation of a proposed approach to incorporate structural condition information obtained from a traffic speed deflection device into the Virginia Department of Transportation (VDOT) pavement management system’s pavement treatment selection process for asphalt pavement sections, which are denoted within the VDOT pavement management system as BIT for bituminous. This study analyzed a subset of the more than 7,000 lane miles tested in Virginia. The subset of data includes the structural condition data on approximately 4,250 lane miles (approximately 1,690 and 2,560 lane miles on the interstate and primary networks, respectively) of the VDOT network. The proposed approach calculates the pavement effective structural number and uses this number to determine the remaining structural life (RSTL). Researchers used RSTL thresholds to determine a structural modified recommended treatment category, that is, the recommended pavement rehabilitation category based on currently used surface condition and adding in the structural condition.
