Recycled Tire Rubber (RTR), from waste tires has been used in asphalt by the paving industry since long time. Recycled Tire Rubber has been used as an asphalt binder modifier and asphalt mixture additive in gap-graded and open-graded asphalt mixtures and surface treatments. The purpose of this course is to provide the information regarding the use of recycled tire rubber to modify asphalt binder and as an additive for asphalt mixtures for practicing highway pavement design professionals. The study material discusses field and laboratory testing methods as well as performance evaluation of the pavement mixtures with RTR. This course is important for transportation engineers and civil engineers who are responsible for overseeing the field and or laboratory testing programs. The Course material is based on FHWA Publication Number FHWA-HIF-14-015: The use of recycled tire rubber to modify asphalt binder and mixtures.

At the conclusion of this course, the learner will have a better understanding of the use of recycled tire rubber to modify asphalt binder and as an additive for asphalt mixtures as well as following:

• Understands process of using RTR as an asphalt binder modifier
• Knowledge of asphalt mixtures and asphalt binder content requirement
• Understanding about various RTR processes used in asphalt pavements
