Michigan Cone Penetrometer Test Calibration

The Michigan Department of Transportation (MDOT) purchased Cone Penetration Test (CPT) equipment in 2019 to better define the geotechnical conditions at project sites. To date, MDOT has used the CPT on 12 sites including the M-66 Monroe Creek Crossing. One year of CPT data has been collected on projects that were also drilled using traditional techniques. A total of 50-55 CPT soundings exists alongside traditional soil borings with visual descriptions and blow counts. Some grain size distribution and other lab tests have been conducted from the soil boring samples. MDOT has graphed some of the data on published soil type behavior charts to note preliminary correlations. However, more statistical comparison is needed to calibrate the Michigan CPT test and identify procedures that should be followed to produce and interpret Michigan soil data reliably. In addition, MDOT could benefit from a standardized procedure that stores data in the Data Interchange for Geotechnical and Geoenvironmental Specialists (DIGGS) data storage format and provides automated output that assists with risk-based design. Further identifying site variability may help with appropriate site characterization and design savings.
