Over the past two years, the Canadian User Group for Pavement ME Design™ has run design trials to become more familiar with the software program and to evaluate the sensitivity of the predicted pavement distresses to different input parameters. A project developed by Manitoba Infrastructure and Transportation was used as the pavement design for all these trials. Results from the previously completed design trials have been reported elsewhere. More recently, the User Group has completed trial runs by varying the design reliability to evaluate the sensitivity of the predicted distresses to the variation in the design reliability. The input reliability was varied from 60 percent to 90 percent, in increments of 10 percent, holding all other inputs constant. This created four alternative scenarios for each climate station. Trial runs were completed for several climate stations across Canada. This paper presents the results of these reliability sensitivity trials and highlights the key findings.
