Recalibration of the PMED Rigid Pavement Models and Integration of the NCHRP 1-51
July 08, 2022Three 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:
- Integrating the results from NCHRP 1-51 on the bonding and interaction between the PCC slab and base layer.
- 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.
- 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.
