Evaluation of Asphalt Rubber and Reclaimed Tire Rubber in Chip Seal Applications

The objective of this study is to improve the durability and to extend the life of chip seal applications in Louisiana using rubber-modified emulsion and reclaimed rubber tires in the aggregate layer. To achieve this objective, the study will review state practices in the use and construction of rubberized chip seal including both asphalt rubber, rubber-modified emulsion, and reclaimed rubber tires in the aggregate layer. Based on this review, job mix formula will be developed for rubberized chip seal and will be evaluated in the laboratory. Crumb rubber will be used as a binder modifier as well as part of the aggregate stone. Construction, short-term field performance, and cost-benefit analysis of this new class of asphalt surface treatment will be evaluated to facilitate implementation in pavement preservation activities.
