Abstract
Biochar can be used as an additive for bitumen. A bitumen composite includes bitumen and biochar. The biochar can include biochar from one or more of algae, food waste, animal waste, and cellulose-containing material (e.g., palm sheath). The biochar typically comprises 1 wt % to 20 wt % of the weight of the bitumen composite. The bitumen composite can be combined with aggregate to yield asphalt.
