Details
Asphalt waste containing coal tar is considered to be hazardous waste where the level of coal tar is >0.1%.
Even when they are treated, normally through encapsulation using a cold recycling bound mixture, they are still considered to be hazardous waste.
Their treatment and subsequent use in construction requires an environmental permit unless the requirements in this guidance are followed.
This RPS is only relevant to the final use of the material.
