Laboratory Evaluation of Storage Stability for CRM Asphalt Binders

This paper conveys the laboratory investigation of storage stability CRM binder as a basic study. The was produced through wet process in laboratory. percentages crumb rubber used for rubberized were 5%, 10%, 15% and 20%. samples prepared according to ASTM D7173. In order evaluate properties each part binders, tests carried out rotational viscosity viscoelasticity, separation index assessed with G*/sin δ %rec. general, results this study revealed that (1) conditioned binders appeared have higher bottom compared middle top parts.; (2) similar results, after conditioning showed highest value part; (3) from MSCR test, Jnr % rec values are observed trend although some data not measured due load than DSR test; (4) it discovered SI generally suitable evaluating asphalt rec.
