Effects of hydrated lime and quarry dust dosage and aging on the relaxation modulus of bituminous mastics [PDF]

open access: yesScientific Reports
Bituminous mastics are essential in influencing the stiffness and viscoelastic behaviour of asphalt mixtures, as the binder–filler matrix governs stress transfer and deformation resistance in pavements.

Simulation of relaxation time and storage modulus for carbon nanotubes-based nanocomposites

open access: yesJournal of Materials Research and Technology, 2021
This paper develops two equations for relaxation time and storage modulus of biopolymer nanocomposites at unlike frequency ranges. The relaxation time is correlated to zero complex viscosity, yield stress, K constant and power-law index. In addition, the

Comparison of Relaxation Modulus Converted from Frequency- and Time-Dependent Viscoelastic Functions through Numerical Methods

open access: yesApplied Sciences, 2018
Due to the difficulty of obtaining relaxation modulus directly from experiments, many interconversion methods from other viscoelastic functions to relaxation modulus were developed in previous years.
