Abstract

Cement concrete (CC) is frequently used for highway pavement as well as for airport runways. Recently, the Falling Weight Deflectometer (FWD) is usually used to access load bearing capacity of the CC pavement. However, the FWD can determine only static modulus of elasticity but not flexural strength of concrete. While the tensile bending strength of cement concrete is an important criteria for the evaluation of cement concrete surface's quality. Therefore, this paper aims to estimate a relation between the modulus of rupture and elastic modulus of CC. The result indicates that the flexural strength and the static modulus of elasticity have a linear relationship with adjusted R quare is 66.0%.
