TAC Pavement ME User Group - Canadian Climate Trials

The major objective of the NCHRP 1-37A project was to develop a document for adaptation by AASHTO as its new Mechanistic-Empirical Pavement Design Guide (MEPDG) for new and rehabilitated pavement structures. The development of the new AASHTO MEPDG and its supporting software DARWin ME (later re-named to Pavement ME Design), has changed existing pavement design procedures, but would need to be adapted and calibrated for local conditions. The Pavements and Soils and Materials Standing Committees of the Transportation Association of Canada initiated a Pool Fund project to provide guidance to Canadian agencies on adaptation and calibration of the MEPDG to Canadian conditions. The calibration process began with the development of a database of historical Canadian climate information for various locations across the country, which has since been included in Pavement ME Design. The user group began running trial designs and comparing the variability in results. A flexible pavement design was provided by Manitoba Infrastructure and Transportation that was used as the base design. This base design was modified for various climate stations across Canada, while keeping all other input parameters consistent. Design trials were then completed by changing the season in which the pavement structure was constructed, followed by evaluating the impact of changing asphalt cement grade in the asphalt mixtures. The objective of this paper is to present the results of the trials completed by the TAC Pavement ME user group, and highlight some of the findings of the analysis.
