“…Thomlinson proposed characteristics to represent nonlinearity of the temperature distribu-tion through the slab thickness in 1940. The nonlinearity in the temperature distribution was theoretically predicted by Thomlinson (5) and Bergstrom (6), and was subsequently proved by experimental data presented by numerous investigators (7)(8)(9)(10). Experimental test slabs were instrumented to analyze the thermal stresses and deformation in the Bates Test Road (11).…”

A concrete slab was constructed at Texas A&M University to study temperature, moisture, and creep effects on the curling and warping behavior of jointed concrete pavements under different curing conditions. A saw-cut joint was placed at the mid-slab location, where one half of the slab was cured with a standard curing compound and the other half was mat-cured. The half of the slab under membrane curing was subjected to a larger built-in curling and shrinkage than the half that was matcured. Because of differences in the amount of shrinkage and creep between the two curing methods during the hardening process, the two halves of the slab showed different early-age behaviors with respect to strain and vertical displacement. The dowels also affected the early-age behavior of the slab at the saw-cut joint. A linear relationship was found among measured vertical corner displacements, concrete strain, and calculated dowel bending moments. The equivalent temperature differences calculated by ISLAB 2000 present the effects of shrinkage and creep on the curling and warping behavior of the slab.

“…Several studies have shown that non-linear temperature variation prevails across the depth of slab and some parts of the concrete slab have a tendency to lift up when a moisture or temperature difference exists across the depth of slab [6] [7][8] [9]. Also, the peak temperature difference occurs only for a short duration.…”

“…It can expand or contract axially, or it can bend with its cross-section remaining plane. The first deformation can be caused by a uniform temperature gradient; the second can be caused by the combined effects of linear temperature gradient and traffic loading (Choubane & Tia, 1995;Tang et al, 1993). The total stress due to critical thermal loading conditions can be obtained by adding algebraically the bending stresses due to a combination of a linear temperature gradient and loading conditions (Choubane & Tia, 1995).…”

The purpose of a rigid pavement design is to determine the thickness of the layers and the quality of the materials used in the pavement. The stresses occurring in a pavement should not exceed the modulus of rupture of the concrete. In this study, the answer to the most reliable and cost-effective solution for a pavement design for a single axle and different temperature gradients was investigated. 3D finite element analysis (FEA) using the ABAQUS package program was carried out with the Taguchi method. A factor, cost to stress difference ratio (Cost/(σ cr − σ max )), was developed to find both the most reliable and the cost-effective solution. The maximum principal stress was calculated by FEA for each of the alternative pavement design. Among the many alternative pavement designs, the solution that gives the minimum cost to stress difference ratio is selected as both the most reliable and cost-effective design.
