Abstract
In the structural design of continuously reinforced concrete pavement (CRCP), thermal stresses should be properly taken into account. In this study, thermal strains and temperatures in a concrete slab were measured on a test section of CRCP. Measured strains were divided into average, curling and nonlinear components and each component was examined. It was found that the curling component is predominant, in trems of transverse stress which is important in the stuructural design. However, the maximum of the thermal stress is reduced by 25% due to the effect of the nonlinear component. Based on the results, a procedure for eatimating the thermal stress in CRCP was proposed and verfied by the measured data.
