• Abstract:
  "The objectives of this research are to establish a resilient modulus test results database and to develop ; correlations for estimating the resilient modulus of Wisconsin fine-grained soils from basic soil properties. A ; laboratory testing program was conducted on representative Wisconsin fine-grained soils to evaluate their ; physical and compaction properties. The resilient modulus of the investigated soils was determined from the ; repeated load triaxial (RLT) test following the AASHTO T307 procedure. The laboratory testing program ; produced a high-quality and consistent test results database. ; The resilient modulus constitutive equation of the mechanistic-empirical pavement design was selected to ; estimate the resilient modulus of Wisconsin fine-grained soils. Material parameters (ki) of the constitutive ; equation were evaluated from RLT test results. Then, statistical analysis was performed to develop correlations ; between basic soil properties and constitutive model parameters (ki). Comparisons of resilient modulus values ; obtained from RLT test and values estimated from the resilient modulus constitutive equations showed that both ; results are in agreement. The correlations developed in this study were able to estimate the resilient modulus of ; the compacted subgrade soils with reasonable accuracy. The proposed material parameters correlations could ; be used to estimate the resilient modulus of Wisconsin fine-grained soils as level II input parameters. Statistical ; analysis on the test results also provided resilient modulus values for the investigated soil types, which can be ; used as Level III input parameters."
