Investigation of fatigue and thermal cracking behavior of rejuvenated reclaimed asphalt pavement binders and mixtures
Source abstract
Abstract
Abstract Bio-based rejuvenators are being under extensive study to enhance the properties of aged binders. Industry professionals and state transportation agencies are wary about incorporating high amounts of reclaimed asphalt pavements (RAP) into new mixtures owing to their high stiffness and low creep rate. In this research, a soybean-derived rejuvenator is used to rejuvenate an extracted stiff RAP binder. The rejuvenator is initially added to a PG58-28 binder using a 12% dosage. The modified PG58-28 is then blended with an extracted RAP binder at a ratio of 1:5. The critical high and low temperatures of the rejuvenated RAP binder are significantly lowered as revealed by the dynamic shear rheometer (DSR) and the bending beam rheometer (BBR) testing. A study of the BBR master curves shows significant improvement in the creep compliance of the rejuvenated RAP binder indicating the ability of the binder to dissipate thermal fatigue loading. The fatigue cracking of the rejuvenated RAP binder is considerably enhanced as suggested by both the fatigue and Glover-Rowe parameters. Disk compact tension (DCT) specimens made of 100% RAP mixed with the modified PG58-28 showed higher fracture energy compared to specimens made of 100% RAP and the neat PG58-28, when tested at −6 °C. To simulate full blending conditions, additional mixtures were prepared using extracted RAP binder blended with the neat PG58-28 and the modified PG58-28, and subsequently mixed with the recovered bare RAP aggregates. These mixtures simulating full blending conditions showed a further increase in fracture energy.
