The use of continuous intrusion miniature cone penetration testing in estimating the resilient modulus of cohesive soils

This paper presents an application of the continuous intrusion miniature cone penetration testing in evaluating the resilient modulus of cohesive soils. Four cohesive soils were selected for the field and laboratory testing program. The field tests were performed on these soils using the continuous intrusion miniature cone penetration test system. The laboratory testing program included repeated load triaxial tests on undisturbed soil samples, and soil physical and strength properties testing. A statistical analysis was performed on the test results of two soils to develop a correlation among the resilient modulus, cone penetration test parameters, in-situ stresses, and soil properties. The model was used to predict the resilient modulus of other two soils. The predicted and measured values of the resilient modulus were in agreement.
