TRB’s National Cooperative Highway Research Program (NCHRP) Research Results Digest 347: A National Database of Subgrade Soil-Water Characteristic Curves and Selected Soil Properties for Use with the MEPDG explores the creation of a national database of pedologic soil families that contains the soil properties for subgrade materials needed as input to the Mechanistic-Empirical Pavement Design Guide (MEPDG).

The report focuses upon the parameters describing the soil-water characteristic curves and also includes measured soil index properties needed by the Enhanced Integrated Climate Model in all three hierarchical levels of pavement design.

NCHRP Web-Only Document 153, which has the same title as NCHRP RRD 347 is the contractor’s final report and Appendices A through D related to NCHRP Research Results Digest 347 of the same title.
