Recalibration of the PMED Rigid Pavement Models and Integration of the NCHRP 1-51

July 08, 2022

Three major enhancements to the PMED software were completed in FY 2022, and all three are included in the new version 3.0.

The three enhancements are:

  1. Integrating the results from NCHRP 1-51 on the bonding and interaction between the PCC slab and base layer.
  2. The MERRA-2 climate interface was integrated into the PMED software. This interface makes getting the climate data much easier with a few clicks of the mouse for any grid point across the world.
  3.  Updating the global calibration for PCC pavements (JPCP and CRCP). An updated global calibration factors for PCC pavements hasn’t been completed for some time. The recalibration efforts used the MERRA-2 climate data available through LTPP InfoPave.
