Abstract
The resilient modulus of granular materials used in base layers is influenced by numerous factors, such as grain-size distribution and aggregate source properties. Resilient modulus tests were performed on three aggregate sources for five identical gradations in order to study their respective effects on the mechanical response of granular materials. To consider these effects, two new parameters associated with frictional properties and gradation are introduced. For the proposed model, standard grain-size distribution and flow tests are needed to estimate of the resilient modulus of granular materials.
