Fracture Energy Method For Determining Stiffness In Polymer Modified Asphalt Binders Using The Single Edge Notched Beam, Alejandro Rosales

McNair Scholars Research Journal

Transverse cracking is a prevalent problem that occurs in asphalt pavement binders in cold climates and diminishes the integrity of the road as well as shortens the life span of the road leading to premature failure. Current specification for testing asphalt pavement binders for transverse cracking fails to accurately model the behavior of modified asphalt binders because it does not take into account the effects of physical hardening. Furthermore, current specification, which employs the use of the bending beam rheometer (BBR) and direct tension tests, was developed through the use of unmodified asphalt pavement binders and so it does not …
