Bimodular Analysis of Hot-Mix Asphalt Semantic Scholar

ABSTRACT In this paper, the bimodular (different tensile and compressive moduli) stress distribution in the IDT specimen is determined for different compressive to tensile modulus ratios. The difference between the modulus calculated from the IDT test assuming Hondros' linear elastic stress distribution, and the compressive and tensile moduli is then obtained.
