Abstract
The paper presents a study of crumb rubber blends aiming at the application in noise reduction. The major issues addressed include the fabrication method in making crumb rubber blends, the tensile strength measures, measurement of the coefficient of acoustic absorption (AAC), surface textures of crumb rubber blends, the analytic analysis on AAC and noise absorption. The results obtained in this study show that crumb rubber blends may present a potentially viable alternative to current concrete highway noise barriers.
