DEMONSTRATION PROJECT NO. 37. DISCARDED TIRES IN HIGHWAY CONSTRUCTION

This project will demonstrate the feasibility of using the rubber from discarded tires in various highway construction and maintenance operations. The project will include the following: a slide tape presentation explaining the general concept of the project; explanation of the project details and answering of pertinent questions; technical assistance for the construction of demonstration installations; and the negotiation of agreements for the construction of these installations with participating agencies. Laboratory and field tests have indicated that the performance of several asphaltic materials can be improved by incorporating proper amounts of recycled rubber. When these materials are applied at select locations, the overall improved performance should economically justify their use. The asphalt rubber materials which show the most promise include seal coats, joint and crack fillers and strain relieving interlayers. A rubberized seal coat can resist reflective cracking when placed over a fatigue cracked surface. The strain relieving interlayer is placed between an existing cracked surface and an overlay. It is primarily intended to reduce and delay the reflection of thermal cracking through thin bituminous concrete overlays.
