“…Equation 4 is the energy-based failure criterion (G R ), which has been proven to be able to determine the failure of mixtures under various loading conditions using the data from three to four fatigue tests (16,20). It was found that the G R versus N f (number of cycles to failure) curves among different types of mixtures-for example, modified binder mixtures, mixtures with a high content of reclaimed asphalt pavement (RAP), and warm-mix asphalt (WMA) mixtures-differ significantly (17,18). One of the major strengths of the S-VECD model is its ability to describe the fatigue performance of an asphalt mixture under a wide range of temperature and loading conditions by using the data from dynamic modulus tests and only three to four fatigue tests.…”

“…The S-VECD model is built on three concepts: (a) the elastic-viscoelastic correspondence principle, which is based on pseudostrain, (b) the continuum damage mechanics-based work potential theory, and (c) the time-temperature superposition principle with growing damage in order to include the combined effects of time and temperature (11)(12)(13)(14). The S-VECD model also includes a newly developed energy-based failure criterion (G R ) that is independent of temperature and loading mode to determine the failure of the mixture (15)(16)(17). Therefore, the LVECD program does not require the assumption of crack initiation a priori because the flexibility of the inherent S-VECD model allows cracks to initiate and propagate wherever the fundamental law suggests; thus, realistic cracking conditions can be reflected by the simulations (18).…”

Mechanistic–empirical pavement design has received significant attention from the pavement community as the method for designing asphalt pavements in the future. Currently available software for mechanistic–empirical pavement design includes the AASHTOWare Pavement ME Design (Pavement ME) program. The Pavement ME program allows users to predict pavement distresses by applying layered elastic theory for the mechanical responses and using empirical models for the distress predictions. The layered viscoelastic pavement design for critical distresses (LVECD) program, which employs three-dimensional viscoelastic finite element analysis with moving loads, can also be used to predict the fatigue and rutting performance of pavements. The LVECD program employs the simplified viscoelastic continuum damage (S-VECD) model as the material model for the fatigue performance predictions of asphalt mixtures under complex loading and environmental conditions. This paper examines and compares the performance of 33 pavement sections from five research projects located in the United States, Canada, and South Korea by using both the Pavement ME and LVECD computer programs. To verify the results obtained from these two programs, the simulations were compared with the field performance data. In terms of ranking, the LVECD simulations provided better agreement with the field performance data than did the Pavement ME simulations. One of the main reasons for the better predictions obtained by the LVECD program is that its fatigue performance predictions depend on the mixture properties of all the layers, whereas the Pavement ME program considers the fatigue properties of only the bottom layer mixture.

“…However, there are relatively few research studies on LSAM fatigue performance, especially on its constitutive model. e applications of the viscoelastic continuum damage (VECD) model for predicting the fatigue performance of asphalt mixtures have been widely used in the past two decades [12][13][14]. Wang and Kim proposed a failure criterion by using the VECD model and considered that the attenuation of the pseudostiffness is a material constant that is independent of the loading mode, temperature, and stress/ strain amplitude [15].…”

The mechanical response characteristics of large stone asphalt mixtures (LSAMs) are key factors in studying its fatigue characteristics during cyclic loading tests. Based on disturbed state concept (DSC) and viscoelastic continuum damage model (VECD), a series of tests using an overlay test (OT) were carried out to investigate the fatigue characteristics of LSAM. The results showed that disturbance and damage increased with decreasing frequency and increasing loading displacement and aging degree, while the asphalt content had no obvious adverse effect on the increase in damage. In addition, the disturbance and damage grew rapidly in the early stage of loading and reduced in the later stage of loading. On the contrary, based on DSC, the constitutive model modified with disturbance function (D) defined by external work could describe the mechanical properties, and the evolution process of disturbance function (D) could reflect the damage change in cyclic loading tests. The research conclusion can enrich the theoretical research on the fatigue failure response and mechanism of LSAM under cyclic loading and expand the application scope of DSC in the field of pavement.

“…Viscoelastic Continuum Damage (VECD) Model is a prevalent approach which has been utilized by many researchers to evaluate fatigue resistance of asphalt mixes (Lee, Kim 1998;Daniel, Kim 2002;Kutay et al 2008;Underwood et al 2010;Sabouri, Kim 2014;Norouzi, Kim 2015). This method is used to differentiate damage from time effects related to viscoelasticity by substituting strain with pseudo-strain (Hintz et al 2011a).…”

“…This method is used to differentiate damage from time effects related to viscoelasticity by substituting strain with pseudo-strain (Hintz et al 2011a). VECD Model has been simplified (namely, S-VECD) and produced on the basis of uniaxial cyclic direct tension test to predict fatigue life of asphalt pavements (Norouzi, Kim 2015;Schapery 1990). This method, then, became a standard procedure and was known as AASHTO TP-107.…”

Fatigue is one of the most occurring distresses in asphalt pavements. Asphalt binder plays a critical role in fatigue behavior of asphalt mixes. Modelling and predicting fatigue behavior of binders will result in more fatigue resistant mixes. In this research, possibility of using Date Seed Ash alongside two commonly used additives (namely, a siliceous and a limestone) as bitumen modifier were investigated. Then, the influence of these additives on fatigue behavior of asphalt binders and mixes was investigated. Linear Amplitude Sweep (LAS) test was carried out and Viscoelastic Continuum Damage (VECD) parameter was determined. In addition, Indirect Tensile Fatigue Test (ITFT) was performed on mixes containing these additives. Correlation equations were developed to link fatigue behavior of binders to those of mixes. The results showed acceptable agreement between binders and mixes fatigue testing results. In addition, with predicted models it was able to obtain the asphalt binders contribution to mixes fatigue resistance. However, in the case of ash modified samples, no good correlation was observed between fatigue behavior of binders and that of mixes.
