Laboratory Services

Road Science have specialised laboratories located throughout New Zealand located in Auckland, Mount Maunganui, Wellington, Christchurch, as well as mobile laboratories.

Testing and Services

Road Science laboratories provide expert construction materials testing, classification, quality assurance, material design, data collection technology, pavement investigation and advice.

Road Science has four permanent IANZ accredited laboratories in Auckland, Mount Maunganui, Wellington and Christchurch, as well as the ability to establish mobile laboratories for specific projects.

In the field you can expect skilled and knowledgeable technicians utilising modern equipment and methods to advise and help you meet your specifications and deliverables.

The experienced laboratory team work to current New Zealand and International test methods to help customers meet NZ Transport Authority, local authority and project specifications.

Each Road Science laboratory is led by a team who have extensive experience in the construction materials testing industry. Each laboratory works collaboratively with the other Road Science teams to share resources and knowledge.

Compliance to Standards

All our laboratories are IANZ accredited to NZS/ISO/ IEC 17025 covering mechanical test sections on:

4.01 Aggregates

4.02 Bituminous Materials

4.04 Concrete

4.08 Soils

4.15 Seconded Sampling

4.20 Pavements

4.99 Site Testing

Advice and Support

When you choose the Road Science Technical Services team you are guaranteed a reliable service with fast turnaround times. The Technical Services team provide more than just test results and data - they can provide technical assistance to help you understand the quality of your materials and pavements for your projects or assist with tenders.


The Road Science laboratories work in collaboration with a team of experts including Dr Greg Arnold - Principal Pavement Engineer and Darcy Rogers - Technical Development Manager. Greg’s team can analyse laboratory test results and interpret them as inputs to pavement design modelling - for predicting performance with comparisons with other standard products. 

Testing and Services

All our laboratories are IANZ accredited to NZS/ISO/IEC 17025 covering mechanical test sections on the adjacent categories.

Road Science labs are accredited for over 200 different test methods including those that are recognised by the industry in New Zealand and offshore.
