Asphalt, Bitumen & Pavement Testing Laboratories
Asphalt testing spans binder characterisation (performance grading, viscosity, aging), mixture design and verification (volumetrics, stability, rutting and cracking indicators) and field control (density, cores, smoothness-adjacent measurements). The applicable programme depends on the specifying agency.
What does it measure?
- Binder performance grading and aging behaviour
- Mix volumetrics: air voids, VMA, density of compacted specimens
- Marshall stability and flow (ASTM D6927) or Superpave gyratory compaction
- Asphalt content and aggregate gradation of recovered mix
- Core density and thickness for acceptance
When is it used?
- Mix design approval and plant verification
- Investigating premature rutting, cracking or raveling
- Acceptance testing of placed pavement
- Evaluating reclaimed asphalt content and recycling options
Sample considerations
- Loose mix, cores and binder samples each have different quantity and conditioning requirements — confirm with the laboratory before sampling.
- Identify the specifying agency and mix designation; test programmes differ between them.

Frequently asked questions
- Do all agencies use the same asphalt tests?
- No. Many highway agencies specify Superpave-based programmes, while others still reference Marshall methods. Always cite the governing specification in your request.
