Prediction of moisture curling of concrete slab

Moisture curling occurs due to non-uniform moisture distribution in a concrete slab. The curled geometry and self-weight of the slab induce undesirable high stress region near the drying surface, and may cause cracks when external wheel loadings are applied. Therefore, alleviating the degree of curling is an important issue in pavement design, and a proper prediction scheme is essential in design process. In this paper, a systematic procedure for predicting moisture curling of slab is presented including material model description, material model calibration, and finite element simulation. The study employs a material model describing elastic response, creep, drying shrinkage, and thermal expansions. The material model is incorporated into a finite element analysis (FEA) code ICON developed at University of Illinois. The material model and prediction scheme were validated with the experimental result of a single slab moisture curling test conducted at the National Airport Pavement Test Facility (NAPTF).
