Stiffness modulus of reclaimed asphalt binder modified with local bio-rejuvenator in Indonesia (dynamic shear rheometer to van der poel nomograph test result)

Abstract This study intends to examine the effect of using bio-rejuvenators (BioCS and BitutechRAP) on Reclaimed Asphalt (RA) binder as seen from asphalt stiffness modulus (Sbit) based laboratory testing Dynamic Shear Rheometer (DSR) Frequency Sweep which is compared Sbit resulting analysis Van der Poel nomograph under RTFO (rolling thin film oven) conditions. The comparison was analyzed by looking at adjustment factor produced each type testing. types binders tested were pen 60/70 control binder, 23% BioCS mixed in RAbinder, 17% BitutechRAP RA binder. results showed that value DSR test not too much different, with an 1.61, addition more influential than BitutechRAP, this indicated + 2.84 close 2.64.
