Dutch cone penetration testing was performed and undisturbed samples were collected at four Kentucky highway sites. Shear strength, as determined by consolidated, undrained triaxial testing of the undisturbed samples, was correlated with friction resistance as measured by the Dutch friction cone. Statistical analysis of all data showed shear strength to be about 80 percent of friction resistance. Recommendations for the use of the Dutch cone penetration test in Kentucky soils were also made.
