Effect of Ground Tire Rubber Particle Size and Grinding Method on Asphalt Binder Properties

The objective of this research was to assess how rubber properties affect the properties of an asphalt binder. This objective was completed by blending eleven unique crumb rubber samples with a singular asphalt binder at a singular loading of 10 percent rubber. Two of the selected rubbers were additionally tested at 15 percent loading. These fourteen GTR asphalt binders were then tested using the performance grade (PG), multiple stress creep recovery (MSCR), cigar tube test, and softening point methodologies.
