This paper demonstrates a simplified method to capture the effect of temperature non-linearity on rigid pavement stress responses utilizing a single parameter (NOLA) and a graphical understanding of temperature non-linearity. This method allows users to easily post-process rigid pavement solutions with linear temperature assumptions to account for these self-equilibrating stresses at any depth in the slab. In addition, this paper also reveals the impact of accounting for self-equilibrating stresses in terms of projected structural fatigue damage at locations along both the top and bottom of the transverse joint and longitudinal edge of a concrete pavement section using a rigid pavement analysis program named RadiCAL.
