Due to the thermoplastic properties of their principle components (bitumen, polyester reinforcements, polymers, fusible plastic film), bitumen waterproofing sheets can be converted into mass bitumen products like road asphalt – significantly reducing the demand for virgin bitumen.
Indeed in the case of high quality waste, bitumen roofing can be recycled to become bitumen sheets once again. When reused to cover roads, bituminous waterproofing sheets thus form a viable and sustainable stockpile of oil constituents.
