“…In the CX test, the number of cycles at failure (N f ) was defined as the cycle at which the phase angle decreases sharply, as this drop is a result of macrocrack localization (Kim et al 2009;Hou 2009). However, the phase-angle-based failure definition cannot be used for predicting fatigue life because the phase angle is not included in the S-VECD model framework (Wang et al 2015). Sabouri and Kim (2014) developed a G R failure criterion for predicting fatigue life by the S-VECD model.…”

“…The parameter jG Ã j • sin δ at intermediate temperatures is generally used to evaluate fatigue performance of asphalt binders. However, this parameter is not a good indicator of the damage resistance because it is only a single point at a small strain level and does not take the traffic loading into account (Wang et al 2015). Considering the disadvantage of jG Ã j • sin δ for evaluating the fatigue performance of binders, the linear amplitude sweep (LAS) method (AASHTO TP101) was developed to estimate damage tolerance of asphalt binders.…”

“…In the standard LAS test (AASHTO TP101), the fatigue-failure criterion is defined as the peak of shear stress. However, some polymer-modified binders did not display obvious peaks of shear stress in the LAS test (Wang et al 2015). Thus, Wang et al (2015) developed the new failure criteria for the LAS test: the peak in stored pseudostrain energy (PSE), which is more desirable to determine fatigue failure.…”

The study investigated the fatigue performance of rubberized stone matrix asphalt (SMA) in the dry process and compared its fatigue characterization with SMAs with other typical binders. Five SMA mixtures were used with the following asphalt binders: (1) virgin asphalt of PG 67-22, (2) crumb rubber modifier (CRM) modified in wet process, (3) CRM modified in dry process, (4) terminal-blend binder, and (5) styrene-butadiene-styrene (SBS) modified binder. Dynamic modulus and direct-tension fatigue tests were performed using the asphalt mixture performance tester (AMPT) system. In addition, improved linear amplitude sweep (LAS) tests were performed on the binders by a dynamic shear rheometer (DSR). The fatigue test data were analyzed by the simplified viscoelastic continuum damage (S-VECD) theory. The results showed that (1) dynamic modulus of the rubberized SMA in the dry process was similar to that of the wet process and higher than that of SMA with virgin asphalt, although a little lower than those of SMAs with terminal-blend binder or SBS binder at high temperatures; (2) the damage resistance and fatigue life of the rubberized SMA in the dry process are higher than those of SMA with virgin asphalt and similar or slightly higher than with the wet process, but lower than SMAs with terminal-blend binder or SBS binder; and (3) the virgin binder had lower damage resistance and fatigue life, followed by the CRM binder in the wet process, the terminal-blend binder and SBS binder had higher damage resistance and fatigue life. This is consistent with the mixture results for the direct-tension fatigue tests.

“…The maximum S Â N is employed in ASTM bending fatigue specification [30] and recently extended to binder fatigue failure analysis [31,32]. The aforementioned phenomenological failure parameters have been shown to correlate well with the onset of macro-cracking when applied to asphalt mixtures and also demonstrated promise for identifying fatigue failure in asphalt binders [33].…”
