Abstract: The design of highway subgrades necessitates the estimation of strength and stiffness characteristics to a reasonably accurate extent. The present study provides details on investigations on the modulus of resilience of lateritic soils in the region of Dakshina Kannada in Southern India, using the cyclic tri-axial test equipment. The discussions also provide comparisons on similar studies performed using the portable falling weight deflectometer (PFWD), and the California bearing ratio (CBR) test. As part of this study, regression equations were developed in order to correlate the observations made using the PFWD and the CBR with the results obtained using the cyclic tri-axial test. It is felt that the regressions developed for estimating the modulus of resilience based on simpler experimental approaches such as the CBR, and the PFWD, will be of special advantage to pavement engineers in developing nations. © 2016, © 2016 Informa UK Limited, trading as Taylor & Francis Group.
