2012-4-26 The viscoelastic property of asphalt mastic was analyzed and tested by uniaxial creep tests in the laboratory and fitted using Burgers model in this paper. Three asphalt mastics, dense graded mixture (DGM), stone mastic asphalt (SMA), and open graded friction course (OGFC), were applied and tested at –10 °C and 15 °C separately.

All characterization of asphalt mixtures must begin with the properties of the mixture in an undamaged state. Subsequent tests of the mixture in different stress or strain states at a level to cause damage can be referred to this undamaged state to assess the degree to which the mixture has been changed.

A new approach for the characterization of linear viscoelastic (LVE) behavior of asphalt concrete is presented in this study. The proposed approach uses the associated function of the original Havriliak-Negami (HN) formulation to model the complex modulus of the material.

This range in modulus is typically obtained between 4 and 88°C at 10 rad/s. This test method is intended for determining the linear viscoelastic properties of asphalt binders as required for specification testing and is not intended as a comprehensive procedure for the full characterization of the viscoelastic properties of asphalt binders.

2022-1-13 asphalt mixtures have been found to be linear viscoelastic for small strains (12). As a viscoelastic material asphalt exhibits a dependency on both time and temperature, characterization of asphalt mixes for design purposes therefore requires that consideration be given to this time - temperature dependency.

Poisson’s ratio, though a vital material property for elastic materials, does not serve the purpose of material characterization for viscoelastic materials like asphalt concrete. This paper presents a brief review of existing literature on the use of Poisson’s ratios in general and by the asphalt research community in specific.
