“…CZM has been employed to simulate crack propagation in asphalt mixes with indirect tension (ID(T)) test (Soares et al 2003), semi-circular bend (SCB) Marasteanu 2005, 2009), three-point bend (SE(B)) or mixed-mode SE(B) (Song et al 2006a(Song et al , 2006b, double edge notchedbar (Tijssens et al 2000) and DC(T) (Wagoner et al 2005a, Song et al 2008) test configurations. An extensive literature review on fracture simulation of bituminous materials using the CZM approach is found in a recent publication of Kim (2011).…”

The durability of asphalt pavements is strongly impaired by cracks, caused primarily by traffic loads and environmental effects. In this work, fracture behaviour of idealised asphalt mixes is investigated. Experiments on idealised asphalt mixes under pure-tension mode (mode I cracking) were performed and fracture parameters were evaluated. In these three-point bend fracture tests, the test variables were temperature and load rate. The test data were stored in an asphalt materials database and special-purpose tools were implemented to analyse and handle the laboratory data automatically. Fracture mechanism maps were constructed, showing the conditions associated with ductile, brittle and ductile -brittle transition regimes of behaviour. The mechanism maps show the failure response of the material in terms of the stress intensity factor, strain energy release rate and J-integral as a function of the temperature-compensated crack mouth opening strain rate. Fracture behaviour of asphalt mix specimens was simulated by cohesive zone model in conjunction with a novel material constitutive model for asphalt mixes. The finite element model agrees well with the experimental results and provides insights into fracture response of the notched asphalt mix beam specimens.

“…Kim & Aragao, 2013; H. Kim & Buttlar, 2009; Y.‐R. Kim et al., 2007; Soares et al., 2003) have demonstrated the ability of CZMs to predict fracture and damage behavior of bituminous materials, mixtures, and pavements. Considering that bituminous media exhibit highly rate‐dependent viscoelastic and nonlinear behavior, cracking can be effectively modeled by the extrinsic nonlinear viscoelastic cohesive zone (NVCZ).…”

Cracking of bituminous materials is one of the main distresses that results in roadway failure. As bituminous media are highly rate‐dependent at intermediate temperatures due to the viscoelastic nature of the binding materials, cracking is also highly rate‐dependent viscoelastic. This presents a clear need to address the phenomenon in the modeling‐analysis process for a more accurate design of mixtures and pavements. This study proposes an advanced computational modeling method to predict complex rate‐dependent cracking in bituminous materials and pavements. In particular, we explored an extrinsic nonlinear viscoelastic cohesive zone (NVCZ) integrated with Gaussian damage evolution. To examine the modeling method and its validity, two modeling efforts in multiple length scales were made: mm‐scale material‐level modeling and cm‐m scale hierarchical modeling that linked the mixture with pavement structure. The NVCZ modeling with Gaussian damage evolution successfully predicted material cracking and damage at different loading rates by using a single set of fracture parameters. This implies that the complex cracking behavior of bituminous materials can be characterized by material‐specific fracture parameters that can be identified by a simple fracture test. The pavement modeling through a parametric analysis demonstrated the sensitivity and capability of the modeling to effectively capture the interrelated influence of several core design variables, such as traffic, material properties, and layer configurations, all of which affect pavement responses and damage evolution. The computational modeling presented in this study has the scientific rigor to predict nonlinear rate‐dependent viscoelastic fracture of bituminous materials and pavements with a good modeling efficiency by significantly reducing laboratory tests.

“…Pertillo and Cebon (2013) conducted a numerical and experimental evaluation of the mechanism of bitumen beams cracking. The researchers performed their experiments on bitumen rather than on the mixture to run the microstructural studies on the pure bitumen fracture (Kim, Y. K., 2011). The fracture parameters used in this study were K IC , G IC , and J integral, which were used to evaluate fracture properties by three-point bending experiment on pure bitumen beams.…”

Fatigue cracking is one of the most important types of failures, which decrease the asphalt pavement service life. Carbon fibers are amongst of the additives that have high tensile strength. It is expected this fiber reduce pavement cracks which increases the fatigue life of pavement. This paper experimentally investigated the effect of the carbon fibers on bitumen specimens. Hence, the effects of fiber characteristics such as length and fiber percentage on the indirect tensile strength and Marshall stability of asphalt mixture were studied. Then, the effect of fibers on bitumen and mastic behavior, which is the main objective of the study, was evaluated. Beam specimens were subjected to three-point bending tests to determine the effect of carbon fibers. Carbon fibers had a positive effect on the tensile strength of bitumen beams at loading rates of 0.5, 2, and 5 mm/min up to 100%. Mastic exhibited a similar behavior to pure bitumen in combination with fibers.
