Coal tar is a by-product derived from coal during the manufacture of domestic town gas. It was commonly used as a binding agent for aggregate used in highways, car parks and paving throughout the UK until circa 1980. This followed the substitution of North Sea gas and closure of town gas works. Bitumen then became the binding agent for macadam and top dressings.

= Disposal =

It is therefore obligatory to carry out tests before digging up such material. These tests will determine:
*Identity and composition in regard to PAH’S.
*Whether is not it is to be classified as waste coming under the Hazardous Waste Regulations Regulations 2005.
*Whether the material can be re-used or has to be sent to a specially designated landfill site for hazardous waste.

Needless to say there are substantial financial implications resting on the outcome of such tests. Early discussion following removal and testing of cores with the Environmental Agency and local planning authority is strongly recommended to establish a strategy for maximum re-use to avoid disposal to landfill.

If the Environmental Agency agrees to its re-use it can be re=processed at a registered and approved plant facility as aggregate in a bitumen bound material such as a cold mix asphalt. The treated asphalt waste containing coal tar will have to meet Specification for Highways Works 900 Series (clause 948) and 800 series (clause 810 to 880).
