Pavement investigation

We deliver professional pavement investigation services to assess surface condition, construction layers, and subgrade performance. Our surveys provide essential data for maintenance planning, rehabilitation design, and new infrastructure development.

What is pavement investigation?

Pavement investigation involves a combination of visual assessment, non-destructive testing, coring, and in-situ testing to evaluate the structure and condition of existing road, runway, or paved surfaces. It helps determine the root causes of surface deterioration, verify pavement composition, and assess whether current materials meet design standards.

This service is essential for:

  • Highway and road resurfacing schemes
  • Airport and industrial pavement assessment
  • Pavement Condition Index (PCI)​
  • Load-bearing capacity checks
  • Lifecycle and asset condition planning
  • Material verification and compliance

Comprehensive testing and reporting

Our multidisciplinary team uses a variety of methods to gather accurate pavement data, including:

  • Core sampling to assess construction layers
  • Falling weight deflectometer (FWD) testing for stiffness
  • Dynamic cone penetration testing (DCPT) for subgrade strength
  • Plate bearing tests to assess load capacity
  • Visual condition surveys and defect mapping
  • Ground Penetrating Radar with coring to assess pavement layer thicknesses​

We combine findings into detailed reports that support design, repair strategies, and funding applications.
