Cracking in asphaltic pavement layers causes primary failure of the roadway structure, and the fracture resistance and characteristics of asphalt mixtures significantly influence the service life of asphaltic roadways. A better understanding of the fracture process is considered a necessary step to the proper development of design-analysis procedures for asphaltic mixtures and pavement structures. However, such effort involves many challenges because of the complex nature of asphaltic materials. In this study, experiments were conducted using uniaxial compressive specimens to characterize the linear viscoelastic properties and semi-circular bending (SCB) specimens to characterize fracture behavior of a typical dense-graded asphalt paving mixture subjected to various loading rates and at different temperatures. The SCB fracture test was also incorporated with a digital image correlation (DIC) system and finite-element model simulations including material viscoelasticity and cohesive-zone fracture to effectively capture local fracture processes and resulting fracture properties. The test results and model simulations clearly demonstrate that: (1) the rate-and temperature-dependent fracture characteristics need to be identified at the local fracture process zone, and (2) the rate-and temperature-dependent fracture properties are necessary in the structural design of asphaltic pavements with which a wide range of strain rates and service temperatures is usually associated.

“…Examples of research efforts considering the viscoelasticity of the bulk material in asphalt mixtures are presented in various studies including Souza et al (2004), Kim et al (2005Kim et al ( , 2006Kim et al ( , 2007, Song et al (2006a), and Aragão et al (2011). More particularly, Kim et al (2005Kim et al ( , 2006Kim et al ( , 2007 have employed the nonlinear viscoelastic CZ model developed by Allen and his colleagues (Yoon andAllen 1999, Allen andSearcy 2001) to simulate the fracture and damage behavior of asphalt mixtures at intermediate temperatures. In order to predict material-specific and rate-dependent viscoelastic fracture of asphalt media, they performed laboratory tests to obtain the linear viscoelastic properties as well as the nonlinear viscoelastic fracture parameters of the asphalt phase and incorporated those parameters into the FEM model.…”

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.
