Abstract	Many researchers have been researching alternative materials to be used as modifiers in asphalt mixtures to improve their properties. This study presents a study of laboratory evaluation of the performance of hot-mixed asphalt (HMA) using crumb rubber as an additive. It is noted that crumb rubber was identified to have potency as a modifier in HMA due to the elastic behavior exposed by the rubber particles, especially in reducing the rutting potential. This research used fine crumb rubber Shred (2.36-0.85 mm) obtained by an ambient-temperature grinding process from discarded truck tires to modify asphalt concrete. The fine crumb rubber with different contents, i.e. 2.5%, 5%, 7.5%, and 10%, was incorporated into the mixture using the dry process method.
