“…The rheology of a soybean oil-derived material soybean acidulated soapstock (SAS) was examined as a potential rejuvenator by bending beam rheometer (BBR), dynamic shear rheometer (DSR), and rotational viscometer (RV) tests [176][177][178]. Using PG 58-28 and PG 64-28, it was found that a small amount of soybean oil (0.75%) can improve fatigue and thermal cracking resistance as it decreases the complex modulus (G*), increases phase angle (δ), increases m-value, and decreases stiffness.…”

“…Most of the asphalt binders have PI values in the range of − 2 and +2. Asphalt binders having PI values less than − 2 are highly temperature susceptible and at low temperatures will be brittle, causing transverse cracking [33].…”

“…The addition of 5% refined cottonseed oil resulted in the greatest reduction in the PG value, from 64 to 52 °C, classifying it as PG 52-XX. Finally, PORTUGAL et al [20] evaluated the behavior of an asphalt mixture with asphalt binder modified with waste and new soybean oil. The results showed that adding 1% of both oils in the base binder improved its physical and rheological characteristics, and a reduction of 2.7 ºC in production temperatures was achieved.…”
