Abstract
The Indian Roads Congress (IRC) design guidelines (IRC: 37-2012 and IRC: 37-2018) for the design of flexible pavement suggest to use resilient modulus (MR) as the key parameter for the design of bituminous pavements. The IRC guideline specifies MR values at different temperatures for different bituminous mixes (dense graded bituminous macadam (DBM) and bituminous concrete (BC)) with modified and unmodified specimens of bitumen binder. As per the Indian codal provisions IRC 37, the MR has been assigned a particular value for bituminous mix prepared with a different bitumen. However, the MR varies differently for different mixes with different binder. Resilient modulus is an important parameter of any material regarding its utilization in building infrastructure. The present study focus on the variation of MR values for BC and DBM mixes with different types of aggregates and bitumen. This study will help the highway engineers to gain the idea about the parameters affecting the resilient modulus.
