AN EXPERIMENTAL STUDY ON THE CONVERSION EQUATION OF K-VALUE AND ELASTIC MODULUS IN CONCRETE PAVEMENT

Abstract

In this study, the conventional relation between K-value and elastic modulus of the Boussinesq's foundation examined from the FEM analysis and the results of the static loading test for concrete pavements conducted at the Public Works Research Institute from 1997 to 1998. From results of the examination, it was found that to obtain the bending stress of concrete slab, a factor of 1.50 must be applied to the coefficient of Vesic's conversion equation.
