Bio-Asphalt

Error creating thumbnail: File missing

Bio-Asphalt can be produced through the pyrolysis of biomass. Among the heavy fractions are ones similar to bitumen and suitable for road paving.

Bioasphalt is derived from biomass (rather than petroleum) via pyrolysis and subsequent processing in a biorefinery. The very heavy and viscous tar-like fractions of Bio-Oil (i.e. "bio-bitumen") may be suitable for road paving and other uses in construction. It is a potentially economical solution to various infrastructure needs. Construction equipment may be the same as for conventional asphalt.
