ELASTIC AND STOCHASTIC CHARACTERISTICS OF CONCRETE FOR RIGID PAVEMENT DESIGN.

This paper summarizes the findings of a study conducted to evaluate the tensile strength, modulus of elasticity, and Poisson's ratio and to determine the variations in these properties in portland cement concrete from in-service pavements in Texas for use in elastic and stochastic pavement design systems. Field cores of concrete from 10 recently completed highway pavement projects in Texas were tested by using the indirect tensile test. Mean values for the tensile strength and modulus of elasticity were established, and the variation about these mean values was estimated.
