  2. Coal Tar Macadam Waste

Coal Tar Macadam Waste Testing

Waste macadams/tarmac need to be classified to the waste regime presently active in the UK.

Request information Download PDF

Coal Tar based macadams and bituminous macadams are classified very differently with the Coal Tar bearing material being classified as a hazardous material (as the Coal Tar content is usually significantly in excess of 0.1%). Bituminous materials are usually classified as Non-Hazardous and as such can be re-used as a product, if processed correctly (e.g. as a 6F3 material), thus classification of the materials can provide substantial savings for the waste producer where 17 03 02 material can be re-used or reprocessed at transfer sites.

WM3 classifies the waste materials as either: 

  • 17 03 01* bituminous mixtures containing coal tar (Hazardous Entry)
  • 17 03 02 bituminous mixtures other than those in 17 03 01* (Non-Hazardous Entry)

It should be noted that 17 03 02 material can be re-used under the WRAP protocol (WRAP Quality Protocol: Aggregates from inert waste) which details out where certain waste materials (as classified under EU Waste Framework Directive 2008/98/EC) can cease to be waste (End of Waste). This material can be used as long as certain criteria (please refer to the protocol) are met, including where the waste:

  • Must not include coal tar or tarred products
  • Must not include freshly mixed bituminous mixtures

 Sampling, Testing and Assessment

Kiwa CMT provide the most robust all-in service with regard to the sampling, logging, testing and assessment in the sector. Our highly experienced staff provide a first-class service in the organisation of sampling and the analytical representation of your macadam-type materials.

We offer on-site coring and extraction of the materials if they are in situ or we can sample stockpiles of materials on site in order to give you confidence in the waste materials that you are producing.

Our comprehensive testing and assessment regime provides robust accuracy in comparison with other test-houses that do not offer the same level of substantial hydrocarbon scrutiny.

Our services include:

  • Coring/Sampling of in situ or stockpiled macadam-type materials
  • Comprehensive and accurate testing to provide accurate levels of Coal Tar present
  • Assessment of the final results and classification of the materials

We at Kiwa CMT can assist by providing independent sampling of your stockpiles (or in situ material) to the relevant sampling standards, a robust testing regime for characterisation and classification, assessment to WM3 and Landfill Waste Acceptance Criteria limits. Our reports clearly classify the materials and are not just outputs of pages of numbers. They also include photographs of the cores, logs of the cores, location maps, test data and assessment data.

How are the reports presented?

Our reports are provided in PDF format via email.
