• 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."
