viscoelastic analysis of sandasphalt mixtures.
VISCOELASTIC ANALYSIS OF SAND-ASPHALT MIXTURES
theory of viscoelasticity is considered as a promising approach to the development of a rational design method for asphaltic mixtures. in an attempt to evaluate the viscoelastic properties of a sand-asphalt mixture, mechanical responses were studied over a wide range of temperatures using static creep tests, stress relaxation tests and constant rate of strain tests.

30/10/2016 The definitions of viscoelastic stress, reference modulus and pseudostrain were rigorously established in the analysis in order to assure that the material properties in the linear viscoelastic stage were the reference properties. As a result, only the linear viscoelastic effect was eliminated when determining the pseudostrain and DPSE in the three stages. With the
