Subgrade Soil Index Properties to Estimate Resilient Modulus for Pavement Design

The focus of this study was to investigate the relevance of soil index properties to estimate, using regression models, resilient modulus of subgrade soil. In 12 sections of prepared subgrade, undisturbed samples were collected employing Shelby tube for resilient modulus testing.Laboratory routine tests were conducted n these samples classifying the soils. The models are verified employing two sets of data comparing measured and predicted moduli. Few relevant conclusions are summarized. The paper concludes that for the range of soils tested, models compiled in this study provide sufficiently reliable predictions of resilient modulus.
