Certain asphalt waste contains Coal Tar which was used as a binder or sealant in past UK road construction in lieu of Bitumen. Coal Tar is deemed hazardous due to elevated levels of PAH’s (Polycyclic Aromatic Hydrocarbons) some of which are carcinogenic. We have seen a sharp rise in requests to help clients manage the hazardous waste that is generated from road maintenance and reconstruction activities.
