Characterizing the Aging and Performance of Asphalt Binder Blends Containing Recycled Materials

The aging of asphalt concrete is mainly governed by the binder, which a naturally occurring organic hydrocarbon. Both chemical and rheological properties binder are expected to change as continues. pavement industry increasing use different recycled materials in construction rehabilitation flexible pavements preserve natural resources, save costs, reduce environmental emissions. aged from alter its characteristics new mix. In this study, 3 virgin base types (PG 64-16, PG 58-22, 70-10) 7 blends containing binders (up 100 % replacement) were subjected conditions. these characterized using dynamic shear rheometer Fourier transform infrared spectroscopy, respectively. It was found that Glover-Rowe parameter distinctively captured with for blends. A good correlation (R2 value 0.83–1.00) observed between properties. source performance grade govern blended binder. Hamburg wheel tracking (for rutting moisture sensitivity) indirect tensile cracking test fracture) tests conducted on mixes maintaining same ratios. laboratory mix parameters correlate well binders. Therefore, can be an important information predicting materials.
