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.
