Abstract

The evaluation of support conditions under jointed concrete pavement slabs is an important input into pavement analyses. Closed-form solutions are available to determine support conditions under the central portion of the slab; however, these solutions assume interior loading (infinite slab) and slab-on-grade conditions.This paper provides corrections necessary to extend these solutions to finite slab sizes.Also provided are closed form solutions for determining foundation support conditions under slab edges and corners using deflection measurements obtained at these locations.
