Development of a Rational Thickness Design Method for Concrete Pavements Analytical Tool Used: FEACONS (Finite Element Analysis of CONcrete Slabs) computer program Factors considered by FEACONS: 1. Subgrade voids beneath slabs. 2. Effects of joints. 3. Looseness of dowel bars. 4. Effects of edges. 5. Temperature differentials in the concrete slabs. 6. Non-linear subgrade response characteristics.

7. Composite slabs made up of two different layers bonded together can be modeled. 8. A stiff base layer between the concrete slab and the subgrade can be modeled. Output of the program: Deflections and stresses due to weight of slabs, temperature effects and applied loads. Modeling a concrete pavement as a three-slab system

A plate bending element is used to model the concrete slab Load transfer at the joints is modeled by a linear spring (for shear transfer) and a torsional spring (for moment transfer)

dowel bars is modeled by a reduction in joint stiffness. The joint stiffness
