Prediction Models of Resilient Modulus for Nongranular Materials
This paper describes an experimental program and the analyses performed for the purpose of developing prediction models of resilient modulus for nongranular materials. Two models were developed and are presented herein. The first model provides a quick estimation of the resilient modulus based on basic characteristics of the specimens, while the second model includes a family of curves that relate a normalized modulus to the resilient axial strains and the plasticity index of the specimens. The significance of the second model is corroborated particularly now that moduli measurements obtained from field and laboratory tests can be easily related.
