Summary:
This paper presents experimental investigation results on rheological and mechanical properties of asphalt binder
containing recycled asphalt pavement.  It also includes evaluation of resistance characteristics against permanent
deformation, fatigue and low temperature cracking.  In present study, two base asphalt binders (AC-10 or PG 58-28 and
AC-20 or PG 64-22) typically used in RI were blended with different amounts of RAP binders obtained from two sources.  
The Dynamic Shear Rheometer was used to evaluate the blended asphalt binders at high temperatures.
