Abstract
This paper is intended to report the results of the two-dimensional elastic analysis for test specimens consisting of two layers: an asphalt mixture to which the beam theory is inapplicable due to its low stiffness, and a thin steel plate on which the mixture is placed. Then, numerical computation has provided the authors with valuable data and information, such as the sizes and shapes of test specimens, friction between the upper and the lower layers, and the stiffness ratio between the two layers. All of these are essential factors in determining the mechanical property of a mixture by using the results of displacement measurement for the purpose of evaluating the elasticity of a pavement mixture.
