Pavements and Concrete Technology

WSP provides independent pavements and concrete testing, investigation and advisory services that help asset owners and project teams understand performance, manage risk and extend the life of critical infrastructure.

We can carry out testing to NZ and/or International Standards. Our tests include quality control testing, random verification testing (RVT), site sampling and testing and specialist advisory services.

Pavements and concrete technology

Reliable pavements and concrete assets depend on more than meeting specifications — they require evidence‑based decisions across their full life cycle. WSP’s pavements and concrete technology specialists provide independent testing, investigation and advisory services that help asset owners, designers and contractors understand performance, manage risk and extend asset life.

From pavement investigations and material characterisation to concrete testing and specialist advice, our teams support informed decisions for roads, bridges, ports and other critical infrastructure. We work to New Zealand and international standards, combining laboratory expertise with site‑based investigations to deliver clear, defensible insights you can rely on.

Pavement Investigations

Pavement quality depth and variability

  • Geotechnical descriptions of material
  • In-situ density
  • Pavement test pits
  • Photographing and logging of pits
  • Sampling of layers
  • Scala in subgrade

If stabilising, which additive to use?

  • Pavement treatment selection with various additives at various % - lime, cement, combination
  • CBR
  • UCS
  • ITS
  • Mix design (T/19)
  • Mix verification

Quality of pavement materials

  • Benkelman beam
  • British pendulum
  • CBR
  • Clay index
  • Gradings
  • Plasticity index

When you need this service

You may need pavements and concrete technology services when you need confidence in asset performance, materials quality or design decisions, including:

  • Assessing existing pavements or concrete assets to understand condition, variability, remaining life or causes of deterioration

  • Verifying materials and construction quality through independent testing to meet New Zealand and international standards

  • Supporting design and rehabilitation decisions with reliable test data and specialist advice

  • Managing risk on complex or high‑value projects, where evidence‑based decisions are critical

  • Resolving performance issues or disputes, including durability, strength, compliance or constructability concerns

  • Testing new or alternative materials, mix designs or treatment options before full‑scale implementation

Our services are commonly used across the planning, design, construction, operation and renewal stages of transport and infrastructure assets, helping clients make informed, defensible decisions at every step.
