Abstract
Data from 96 resilient modulus laboratory tests on four base materials and four subgrade soils was used to develop a predictive model capable of estimating changes in resilient modulus as a function of changes in the state of stress, moisture and density. Test specimens were compacted at optimum moisture/density conditions and then dried or soaked to various moisture conditions. Both standard and modified compactive efforts were used. Plastic, subgrade-type soils were especially affected by moisture. Non-plastic, base-type materials were more sensitive to changes in the state of stress.
