• Abstract:
  A mechanistic-empirical (ME) pavement design procedure allows for analyzing and selecting pavement structures based ; on predicted distress progression resulting from stresses and strains within the pavement over its design life. The Virginia ; Department of Transportation (VDOT) has been working toward implementing ME design by characterizing traffic and materials ; inputs, training with the models and design software, and analyzing current pavement designs in AASHTOware Pavement ME ; Design software. ; This study compared the measured performance of asphalt and continuously reinforced concrete pavements (CRCP) ; from VDOT’s Pavement Management System (PMS) records to the predicted performance in AASHTOware Pavement ME ; Design. Model coefficients in the software were adjusted to match the predicted asphalt pavement permanent deformation, ; asphalt bottom-up fatigue cracking, and CRCP punchout outputs to the measured values from PMS records. Values for reliability, ; design life inputs, and distress limits were identified as a starting point for VDOT to consider when using AASHTOware ; Pavement ME Design through consideration of national guidelines, existing VDOT standards, PMS rating formulas, typical ; pavement performance at time of overlay, and the data used for local calibration. ; The model calibration coefficients and design requirement values recommended in this study can be used by VDOT with ; AASHTOware Pavement ME Design as a starting point to implement the software for design, which should allow for more ; optimized pavement structures and improve the long-term performance of pavements in Virginia.
