Advice and Support

The laboratories provide expert advice regarding quality assurance, material design, testing, and pavement investigation.

The experienced, knowledgeable and professional laboratory team at Road Science help customers meet New Zealand Transport Authority (NZTA), local authority and project specifications.

When you choose Road Science laboratories you are guaranteed a reliable service with a fast turnaround. The laboratory team will provide more than just test results and data - they will give you technical assistance and analysis of the results for your projects or tenders.

The lab team provides technical support for projects, from initial tender and design phase, right through to quality control and compliance testing during the construction phase.

Road Science laboratories are also supported by a team of experts including Dr Greg Arnold. This team can interpret lab test results into such things as pavement design criteria - for predicting performance with comparisons with other standard products. This added value service can be provided at no extra cost.

National Services


Road Science has two high speed data surveying vehicles the Hawkeye 1000, and the Hawkeye 2000.

These vehicles are operated by Road Science’s highly skilled technicians who survey roads right throughout New Zealand.

The Hawkeye system comprises the latest digital camera technology and produces crisp, high-resolution video frames to ensure a continuous digital record of the roadway. The calibrated video cameras accurately log digital images of roadside assets against other parameters such as distance and GPS.

Benefits of the Hawkeye include:

  • Visual outputs from dedicated software and high resolution cameras, which allow for office based site analysis and observations.
  • High speed data collection reduces costs and decreases the delivery of data timeframes.
  • Data is linked to chainage and GPS coordinates, simplifying location of data and features.
  • Data is provided in a format that is able to be directly uploaded into office software.

Hawkeye complies with the following international standards:

  • ASTM E950: Longitudinal profile
  • AASHTO PP37: Pavement roughness
  • ASTM E1845: Pavement macrotexture
  • ISO 13473: Mean Profile Depth (MPD)



Road Science has re-locatable mobile laboratories which are equipped to provide IANZ accredited testing of soils, aggregates, concrete and asphalt for specific project work.

The mobile laboratories can also act as a base for the field testing offered by Road Science.

To enquire about our mobile laboratories please contact the National Laboratory Manager, Janet Jackson.
