dc.description.abstractThe purpose of this study is to evaluate the impact of CRM (Crumb Rubber Modifier) particle size on storage stability and the tests required for its characterization. In this experimental analysis, PG64-22 containing three rubber crumb particle sizes (≤0.5 mm, ≤1 mm, and 1-2mm) was blended individually using a low shear mixer at the same proportion of 10% by weight of the original binder. Based on the analytical results (1), the Superpave test method was selected as the ideal test method and the G*/Sin δ and % Recovery tests performed on the Dynamic Shear Rheometer (DSR) were used to investigate the Separation Index (SI). (2) particle size after conditioning showed a direct effect on SI; (3) SI index values were found to be higher at the bottom than at the top and middle of the sample parts.
