Target Completion Date: June 30, 2026 Pavements
In 2018, the Virginia Department of Transportation (VDOT) officially implemented the AASHTOWare-ME version 2.2.6 as the pavement design methodology for designing all new construction, reconstruction, and pavement widening projects including Interstate, Primary, and Secondary routes with an Annual Average Daily Traffic (AADT) greater than 10,000. With the phasing out of the desktop version and its related services imminent, and the vital role the software plays in the management of the VDOT pavement network, preparing for the transition to the web-based version is key. Like the research conducted at the beginning of ME implementation, it is important to determine the local calibrations based on the web-based version and design criteria values and update the material properties and climate data to create a better model of the pavement structure for more economical, resilient, and practical pavement designs. The purpose of this study is to determine the local calibration coefficients for the relevant distress transfer functions that best reflect the observed pavement performance within VDOT’s network.
