The production of new asphalt requires the combination of mining, refining, and mixing raw materials. Rocks are crushed and blended into specific aggregates and crude oil is refined into bitumen as a binder. As a recycled material, asphalt millings offer substantial cost savings by eliminating a large portion of this production process.
In this study, an optimization process is applied using the Los Angles test machine through the conducted Ball Milling Method (BMM). During the BMM process, various combinations of rotation (R) (100–200-300-400-500) and the steel ball (S) (0-2-5-7-10-12) applied to the recycled aggregate.
