Materials testing & quality control

Where every mix earns its place on the road.

Our accredited laboratory tests asphalt, aggregates, binders and pavement systems — pairing Superpave and Marshall methods with modern performance testing for a complete, defensible picture of how materials behave under traffic and climate.

Inside the lab

State-of-the-art facilities, 140+ years of bench experience.

Binder, aggregate, volumetric and performance testing all happen under one roof, run by certified technicians. From routine acceptance to advanced research, our laboratory team brings more than 140 combined years to your samples.

Beyond routine

Advanced characterisation & forensic diagnostics.

When a project needs more than routine acceptance, we bring research-grade tools — coring and field-core analysis, Scanning Electron Microscopy (SEM), viscosity profiling and modified-binder characterisation, including recycled and rubberized materials.

  • SEM of CRM

    Ambient vs. cryogenic particle morphology.

  • Viscosity profiling

    Patented VR polymer vs. industry modifiers.

  • Coring & field cores

    In-place density and distress diagnosis.

  • Concrete testing

    Companion materials, one accountable lab.
