Rheological evaluation of pg 64–22 asphalt binder modified with lignin of pinus and eucalyptus woods

Lignin is a natural polymer and the second-most abundant material in the plant kingdom containing antioxidant properties. Research using lignin asphalt binder modifications aims to improve asphalt mixture properties, enhance aging resistance, reduce rutting, and extend fatigue lifespan. This research aims to study PG 64–22 binders with two lignin modifications, Pinus and Eucalyptus, in differing amounts. Rheological properties were studied and Fourier-transform infrared spectroscopy analysis tests for discovering chemical composition were performed. The results indicate the viability of modification by incorporating lignin into asphalt binders based on factors such as fatigue lifespan, rutting resistance, and a delayed short-term aging process.
