Study on the Meclidilical Behaviour of Precast Concrete Pavements

Precast concrete pavements (PCCP) are constructed by placing small size precast concrete slabs on the subbase. In this paper, the loading and warping stresses are discussed based on the results of the experiment and FEM analysis. A test pavement was constructed using 1 - 3 m size and 150 mm thick precast concrete slabs. Strains due to wheel load and thermal changes were measured in the test pavement. A FEM model taking the nonlinearity due to lifting up of the slab into account was developed and verified by analysing the measured data.
