Enhanced in-situ measurement and evaluation methods for subgrade modulus utilizing falling weight deflectometer

Falling weight deflectometer (FWD) tests have gained increasing popularity in evaluating the stiffness modulus of a pavement subgrade. This paper presents an enhanced method for in-situ testing and evaluation of subgrade moduli using FWD apparatus. The method comprises three components: 1) guideline...
