Asphalt binder with crude sterols for slower aging rate
A recently granted patent (Publication Number: US11912874B2) discloses a method for slowing the aging rate of aged asphalt binder in a paved surface. The method involves adding a crude sterol containing at least 13.5 wt. % sterol molecules to an asphalt binder composition, which includes a combination of virgin asphalt binder, reclaimed asphalt binder material from aged pavement, and the crude sterol. This asphalt binder composition is then mixed with aggregate to create a paving mix, which is applied to a base surface to provide a paved surface with a slower aging rate. The crude sterol can be derived from bio-based sources like soybean oil or corn oil, or even from cholesterol, and is added in specific proportions to achieve the desired effect.
Furthermore, the patent also covers a method for reusing reclaimed asphalt binder for asphalt pavement production. This involves forming the paving mix as described earlier and applying it to a base surface to create the asphalt pavement. The reclaimed asphalt binder material can come from either reclaimed asphalt pavement or reclaimed asphalt shingles. The process may also include compacting the paving mix applied to the base surface to ensure proper integration and performance of the asphalt pavement. Overall, these methods offer innovative solutions for enhancing the longevity and performance of asphalt pavements by utilizing crude sterols and reclaimed materials effectively in the asphalt binder composition.
