This paper presents the results of a study of AC-BC asphalt mixture with reclaimed asphalt pavement (RAP) and produced by warm mix method. 30% of RAP was combined with new aggregate in mixture. Rejuvenating agent Cyclogen L was used to activate RAP asphalt binder. With 3% Sasobit, temperature of mixing and paving was set at 135°C and 123°C, 30°C lower than conventional mixture with unmodified asphalt binder 60/70 penetration. Three mixture was set in this research, i.e. hot mix asphalt conventional mixture (namely control mix), warm mix asphalt mixture ( SASO) and warm mix asphalt with RAP (SASO RAP). OBC for each mixture was 5,2%, 5,2% and 5,3% for control, SASO and SASO RAP respectively. Regarding the result of resilient modulus and fatigue resistance test, the SASO and SASO RAP showed a better performance than conventional asphalt mixture.
