Fracture Characteristics of Asphalt Concrete in Mode I, Mode II, and Mixed-Mode
… Mixed-Mode testing of asphalt concrete, but only Crack Mouth Opening Displacement (CMOD) was used. This research captured the Crack Tip Opening Displacement (CTOD) and Crack Tip Sliding Displacement (CTSD) in addition to CMOD. This allowed the comparison of three different values of fracture …

Use of phase angle in lieu of critical crack tip opening displacement for asphalt binder specification
… limits can be used in lieu of Critical Crack Tip Opening Displacement (CTOD) as a more practical asphalt binder acceptance property. Two sets of binders were tested using the Dynamic Shear Rheometer to determine the resistance to fatigue cracking, permanent deformation, performance at …

Fracture of Asphalt Concrete: A Cohesive Zone Modeling Approach Considering Viscoelastic Effects
… are proposed. A new operational definition of crack tip opening displacement (CTOD), called delta25, is employed to considerably minimize the contribution of bulk material in measuring fracture energy. Predicted numerical results match well with experimental results without calibration. …

EXPLORING THE MASTER CURVE PARAMETERS FOR EFFICIENT PERFORMANCE GRADING OF ASPHALT BINDERS FROM THE UNITED STATES OF AMERICA
… (EBBR) test is used to determine low-temperature cracking performance, and the Double-Edge-Notched Tension (DENT) test is used to measure the ductile strain tolerance. These tests are time consuming and require a larger sample quantity, even though they are rigorous and accurate. Hence, the study …
