Application of Euler-Bernoulli Beam on Winkler Foundation for Highway Pavement on Expansive Soils
Pavement resting on expansive soil experience longitudinal cracks due to the volume change of subgrade soil. A simple method is expected by engineers to analyze the distress of pavement on expansive soils. In this research, a new method is proposed to analyze a pavement on expansive soil, where the soil is considered as the Winkler foundation and the pavement as a Euler-Bernoulli beam. The key achievement of this method is the introduction of virtual load (q), which transform the problem of pavement on expansive soil to the problem of pavement on regular (non-expansive) soil. The method is validated by using the field data of a highway in Texas which was resting on expansive soil. After comparing the numerical results with the field observation, the location of the maximum bending moment from the closed-form solution was consistent with the actual locations of the longitudinal cracks on the pavement.
