Evaluation of Crumb Rubber in Hot Mix Asphalt

An asphalt-rubber hot mix asphalt (AR-HMA) design was created using a Superpave 12.5mm gradation and a #30 (-) mesh crumb rubber at 20% total weight of the asphalt binder. At this point in time, asphalt rubber has only been used with HMA that contains a more open graded nature, such as open graded friction course (OGFC).
