The Influence of Mortar’s Poisson Ratio and Viscous Properties on Effective Stiffness and Anisotropy of Asphalt Mixture

Abstract: This paper presents the results of a research study and analysis conducted to determine the degree of anisotropy of asphalt concrete in terms of its initial elastic properties. The analysis of asphalt concrete was focused on determining the effective constrained stiffness modulus in three mutually perpendicular directions based on the finite element method. The internal structure of the asphalt concrete was divided into the mortar phase and the mineral aggregate phase. Static creep tests using the Bending Beam… Show more

“…Such complexity can pose notable challenges for machine learning predictions. A high Poisson ratio suggests an increased potential for localized shear strain within the heterogeneous structure of concrete [47,[49][50][51]. This localization, in turn, obstructs the establishment of a precise and consistent relationship among the dynamic moduli and compressive strength.…”
