Resilient Modulus of Asphalt Concrete

D. N. Little / W. W. Crockford / V. K. R. Gaddam

The 'resilient modulus' of asphalt concrete is a single number that is used to describe material behavior and to predict pavement performance in many pavement design procedures. It is analogous to Young's modulus in the small strain theory of elasticity, which is one of two parameters needed to fully characterize a linear elastic, rate-independent material. The second parameter is Poisson's ratio. Several techniques exist for determining resilient modulus. The most common methods are dynamic laboratory tests and nondestructive field tests (NDT). New devices for laboratory testing were developed during this project to address the laboratory needs of the AASHTO Guide and to corroborate NDT results.
