Abstract
Temperature profile and corresponding stresses in concrete pavement were investigated on prototype scale. Four prototypes were considered, conventional and 25%, 50% and 75% of fine-Reclaimed Asphalt Pavement (RAP) inclusive concrete mixes. The observed temperature profile during 270-days was nonlinear with higher degree of nonlinearity for conventional mixes. The profile could be represented in quadratic form which annuls the assumption of linear temperature variation in numerous design methodologies. The total temperature stresses were lower for RAP inclusive prototypes. Stresses with linear temperature profile assumption over or under-estimated and failed to identify the nature of the stress due to actual temperature profile.
