Effect of Ground Tire Rubber Particles on Open-Graded Mixture Performance

The objective of this research was to assess how ground tire rubber (GTR) asphalt modifiers, also known as crumb rubber, affected the design and performance of open-graded friction course (OGFC) mixtures. This was completed by comparing six different GTR modified asphalts and designing similar OGFC mixtures with the modified binders. The mixtures were then subjected to performance tests to compare their performance to a control OGFC which used a polymer-modified asphalt binder.
