This paper derives an analytical solution for a three-slab concrete pavement system resting on a Pasternak (1954) foundation. Joint transfer between slabs is considered in the analysis. The basic equations are based on Reissner's (1945) thick-plate theory and modified to include the Pasternak (1954) foundation model. The transverse shear deformation in the slabs and the transverse connection in the foundation are considered in the three-thick-plate model. The solution of the three-thick-plate system are arrived at by considering the solutions of three elemental plates, one with four guided-support edges and two with two guided-support edges and two free edges. For each slab of the three-slab system, its solution is obtained by superposing the solutions of appropriate elemental plates. The central slab can be represented by superposing three elemental thick plates, while the two-edge slabs are each represented by four-elemental-thick plates. The derived solutions were verified using numerical examples against solutions by finite-element methods.
