Abstract

The objectives of this initial study were 1) investigate the relationship between resilient modulus and R-value; and 2) develop a predictive equation for resilient modulus based on easily measured soil properties. Thirteen different fine-graded soils were investigated. Based on the test results, two multiple linear regression models for predicting resilient modulus are proposed. This study is the first to provide highway engineers in Wyoming with reliable information on the resilient modulus of representative subgrade soils.
