“…The authors also show that their nonlinear elastic behavior (similar to granular materials and characterized by stress dependency [12]) tends to be highlighted during the first phase, http://dx.doi.org/10.1016/j.conbuildmat.2015.07.004 0950-0618/Ó 2015 Elsevier Ltd. All rights reserved. and their visco-elasto-plastic behavior (similar to HMA and characterized by dependence on temperature and frequency of loading [13]) becomes more significant during the second phase. The former behavior is best studied using triaxial tests, such as unbound granular materials, and the latter can be assessed using typical HMA tests, such as indirect tensile stiffness modulus (ITSM) or dynamic modulus |E ⁄ | tests.…”

Since asphalt binder modifiers for the performance improvement have both good and bad effects on the performance of asphalt pavements, it is important to consider all performance parameters of asphalt pavements for the development of modifiers. This paper evaluates the viscoelastic and plastic properties of four types of asphalt mixtures (three modified mixtures and one unmodified mixture) by laboratory tests, and then, the test results are employed to investigate the effects of modifiers. Test methods adopted in this study are the dynamic modulus test for linear viscoelastic model classified as nondefective test and tension test for constant crosshead rate test and cyclic load test and the triaxial compression test for plastic deformation classified as defective test. The performance for the fatigue failure at the real site’s pavement was evaluated by using the VECD-FEP++. The performance of rutting for each mixture was evaluated by using the viscoplastic model from tension test and triaxial compression test proposed by NCHRP 1-37 A MEPDG (AASHTO2004) and the rutting model. The findings from this study support general understanding of the effects of asphalt binder modifier on the fatigue cracking and rutting performance. When considering the performances of rutting and fatigue failure, K2 mixture is the best SBS-modified material. The modified agent for K1 mixture has low performance than K2 mixture, and K4 mixture is good when the rutting is terribly occurred. But it needs serious caution to the failure.

“…Another interesting observation unique to uniaxial compression was that the low points of C ve were progressively decreasing from cycle to cycle. Recently, Yun and Kim (2013) reported findings from uniaxial compression consisting of monotonically increasing loads. They demonstrated that pseudo-stiffness increases after an initial drop, which is in complete tune with the above-described C ve behaviour.…”

The behaviour under load of asphalt concrete (AC) was viewed as additively separable into viscoelastic and viscoplastic components, and the study focused on modelling the pre-peak response of the viscoelastic part under constant temperature conditions. Non-linear viscoelastic behaviour was first exposed in several test modes, and a constitutive theory was subsequently offered -potentially capable of capturing and reproducing the observations. The modelling was based on replacing applied stresses in the linear convolution formulation with effective stresses; it included a mechanism for simulating the following effects: (i) short-lasting damage, (ii) long-lasting damage, (iii) stiffening under compressive conditions and (iv) healing during recovery intervals. As an initial validation effort, the model's reproducibility was assessed by calibration to a uniaxial compression experiment consisting of both small and medium strain levels. Next, the calibrated model was employed to forecast small-strain behaviour in a standard complex modulus test. The simulated results qualitatively agree with recently reported findings that challenge the existence of a linear viscoelastic domain for AC.
