“…Rather, the average dissipation caused by these microcracks is accounted for at the mesoscale of the composite by including irreversibility phenomenologically. Several researchers have characterized the behavior of asphaltic binder using this approach (Kim and Little 1990;Kim et al 1995;Park et al 1996;Lee et al 2000).…”

“…The fracture resistance of asphalt materials significantly influences the service life of asphalt pavements and consequently the maintenance and management of the pavement network. Probably, the most developed and successful approach for modeling damage evolution in bituminous materials is the continuum damage mechanics (CDM) approach, as many researchers (Kim and Little 1990, Park et al 1996, Lee et al 2000, 2003, Chehab et al 2002, 2003, Daniel and Kim 2002, Gibson et al 2003, Tashman et al 2004, Chehab and Kim 2005, Masad et al 2005, Darabi et al 2011) have studied. More specifically, researchers (Chehab et al 2002, 2003, Darabi et al 2011) took into account the major components of asphalt mixture behavior (elastic, viscoelastic, plastic, and viscoplastic) based on a work potential theory, the elastic-viscoelastic correspondence principle, time-temperature superposition with growing damage and a strain-hardening model for viscoplastic behavior to demonstrate good agreement between model predictions and asphalt mixture performance testing results.…”

Cohesive zone (CZ) modeling has been receiving increasing attention from the asphaltic materials and pavement mechanics community as a mechanistic approach to model crack initiation and propagation in materials and structures. The CZ model provides a powerful and efficient tool that can be easily implemented in existing computational methods for brittle, quasi-brittle, and ductile failure as well as interfacial fracture, all of which are frequently observed in asphaltic materials. Accordingly, this paper introduces the CZ modeling approach in the form of a state-of-the-art review addressing the concept of CZ modeling, CZ constitutive relations, their implementation into computational methods, and up-to-date applications of CZ modeling to bituminous mixtures and pavement structures. This paper also includes a brief discussion on the current challenges that researchers face and the future directions to the modeling of fracture in bituminous materials and pavements. CZ modeling is not a topic that can be possibly discussed in a single article; therefore, it should be clearly noted that this review primarily attempts to deliver some of the core aspects of CZ modeling in the area of bituminous composites.

“…and Kim Y.R. [14][15][16][17], has been applied by other researchers for the characterization of asphalt concrete fatigue considering non-linear strain and healing [18,19]. In the VECD approach, the physical strain and physical stiffness of the viscoelastic material (asphalt concrete) are replaced for their pseudo similarities, i.e., for pseudo strain and pseudo stiffness, respectively, which are varied from one loading cycle to another.…”

Abstract:The expression is obtained for determination of cyclic tensile strength for asphalt concrete, which considers damage accumulation and history of loading, using the long-term strength curve for asphalt concrete obtained according to the test results of more than 110 samples to failure at stresses from 0.05 to 0.31 MPa and by introduction of damage kernel in this paper. Cyclic strength depends on the stress, parameters of long-term strength, frequency of loading, durations of loading and relax periods, and ratio of loading period to the long-term strength. Evaluation of accuracy for the obtained expression for the cyclic strength has been performed by comparison with the results of a series for experimental tests of asphalt concrete samples at a temperature of 22 • C and cyclic loading conditions. The stress is 0.31 MPa, and the durations of loading and relax periods are 5 and 60 s, respectively. Calculations performed with the obtained expressions at real road conditions (the stress is 0.31 MPa, and the durations of loading and relax periods are 0.1 and 9.9 s respectively) showed the possibility of its use for the prediction of fatigue (multicyclic) strength of an asphalt concrete pavement for a highway.
