South Dakota Granular Moisture-Density Curve Development and Dynamic Cone Penetrometer Implementation

The Ohio moisture-density curves used by the South Dakota Department of Transportation (SDDOT) were not developed specifically for South Dakota’s granular materials. Previous SDDOT research projects, SD2014-12 and SD2019-05, developed new moisture-density curves; however, these curves are not useable in their current form and further refinement is needed. Further recommendations from this previous research suggested SDDOT use a strength-based testing procedure for granular materials. Based on the results of this previous research, SDDOT has decided to refine the new granular moisture-density curves and implement a field density testing procedure using the Dynamic Cone Penetrometer (DCP). Currently, SDDOT does not have the resources available to analyze the additional available test results and refine the new moisture-density curves or to develop DCP specifications. Additional work is needed to digitize the moisture-density curves to incorporate into the Department’s testing software.
