Resilient modulus of black cotton soil

International Journal of Pavement Research and Technology, 2017
Abstract Resilient modulus ( M R ) values of pavement layers are the basic input parameters for the design of pavements with multiple layers in the current mechanistic empirical pavement design guidelines. As the laboratory determination of resilient modulus is costly, time consuming and cumbersome, several empirical models are developed for the ...
