• Abstract:
  The objective of this study was to investigate the effect of moisture content and dry unit weight on the resilient characteristics of subgrade soil predicted by the cone penetration test. An experimental program was conducted in which cone penetration tests, repeated load triaxial tests, and soil property tests were performed. An experimental setup was fabricated to conduct laboratory cone penetration tests on compacted soil samples. Four soil types and three levels of moisture contents - dry side, optimum, and wet side - were selected for these testings. The results of the laboratory tests were used to validate the prediction models developed during phase I of this research. The application of the cone penetration test in evaluating subgrade soil resilient modulus was successful.
