Application of Nonlinear Fracture Mechanics in Asphalt Concretes
Application of nonlinear fracture mechanics for asphalt mixtures is discussed in this chapter. For this purpose, two nonlinear methods including fracture energy and J-integral are usually used to characterize the fracture resistance of asphalt mixtures. Generally, three different tests including SCB, DC(T), and SENB have been well developed in the past years to determine the fracture energy. These tests are described herein in detail. Furthermore, to calculate the critical value of J-integral, Jc, the specimens with at least two different notch lengths are required to be tested. Strain energy for each notch length is obtained by calculating the area under the load–displacement curve to the failure point. The strain energy versus the notch length is then plotted. The slope of the fitting line represents the Jc value.
