Abstract: Abstract This paper investigates how ultraviolet and oxidative aging affects physiochemical and rheological properties of bio-modified binders containing different bio-oils extracted from biomass (wood pellet, miscanthus, corn stover, and animal waste). Oxidative aging was done… read more here.
