Coal Tar Testing for Reclaimed Asphalt Across England, Scotland & Wales
The ADEPT guidance for managing reclaimed asphalt provides a structured approach for identifying, testing, and classifying materials that may contain coal tar. Coal tar is a hazardous substance, and its presence significantly affects how reclaimed asphalt can be handled, reused, or disposed of. The ADEPT standard supports a consistent, evidence-based process for highway authorities and contractors.
Purpose of Testing
-
To determine whether reclaimed asphalt contains coal tar and, if so, at what concentration.
-
To classify the material correctly for reuse, recycling, or disposal.
-
To support compliance with environmental legislation and duty of care obligations.
Testing Approach
Coal tar identification under ADEPT typically follows a tiered methodology:

Classification of Material
| Category | Description | Implications |
|---|---|---|
|
Non‑tar bound asphalt
|
PAH levels below ADEPT thresholds | Can typically be reused or recycled as standard asphalt |
|
Tar‑containing asphalt (TCA)
|
Elevated PAH levels or confirmed coal tar | Classified as hazardous; strict controls apply |
|
High‑tar material
|
Very high PAH concentrations | Requires specialist handling and disposal |
Management Requirements
If coal tar is confirmed:
-
Material must be segregated and stored separately.
-
Reuse options are limited and must follow environmental permitting rules.
-
Transport must comply with hazardous waste regulations.
-
Disposal typically requires a permitted hazardous waste facility.
-
Duty of care documentation and waste classification records must be maintained.

Dear The Testing Lab PLC,
Many thanks for your prompt and professional asbestos survey report service, I would not hesitate to recommend your company in this regard.
This must be an absolute record for getting a report back, considering the surveyor arrived around 3pm – very well done!
Thank you for the very quick response for the quote and scheduling the survey. There’s never any fuss, and always straight forward. Thanks again.
Thank you for offering such a prompt turnaround for ACM testing and for your courteous service in doing so – I had a nervous client to placate and knowing the report would be back with them in such a short time was very reassuring to them, and for no more than a basic service from the competition!
Bradley, thank you for your efforts at short notice today, please pass on our gratitude to your surveyor Tim who did your company proud!
Thank you very much for the air sampling results – and please accept our grateful thanks for resolving this issue so quickly and for the promptness of the report.
Your analyst, Lee, was very helpful and his suggestions and advice appreciated.
We would have no hesitation in recommending The Testing Lab and will be in touch soon with regards arrangements for a full asbestos survey for the rest of the site.
TTL have been working directly as my analyst for the last 12 months on a very complex asbestos removal scheme, they have achieved all of their KPI’s without fail and on a number of occasions surpassed their SLA in acting for us on planning issues associated with the demolition in regard to contamination which cannot be removed as part of the normal sequence of operation.
There reports are always issued within timescales and they have policed the reports by the Licensed asbestos contractor faultlessly sometimes in very difficult circumstances.
