摘要: Resilient modulus (M R) of subgrade soils is the elastic based on recoverable strain under repeated loads and depends several factors such as soil properties, type stress states. This paper presents prediction equations to estimate M R from a set physical properties for unified classification system types namely coarse-grained fine-grained soils. Data extracted long-term pavement performance information management database 259 test specimens reconstituted samples 19 states in New England nearby regions USA two provinces Canada were used this study. Generalised constitutive model consisting bulk octahedral shear was predict by developing regression coefficients (k-coefficients) that relates them various properties. Prediction models developed conducting multiple linear analy...
