Abstract
In this paper, the thermal stress of precast concrete pavement (PCCP) is discussed based on the experiment and FEM analysis. The thermal strains measured in the test pavement were divided into three components; axial, warping and nonlinear components, and examined by FEM. Axial and nonlinear components were small in the term of tensile stress, and could be neglected in the structural design. On the other hand, warping component was found to be significant and could be estimated by FEM with appropriate subbase model.
