A laboratory study was undertaken to determine the effect of grading/particle size distribution on permanent deformation in multi-stage repeated load triaxial (RLT) tests.

The research systematically compared the driving performance and conversational patterns of drivers speaking with in-car passengers, handsfree cellphones, and remote passengers who could see the driver’s current driving situation (via a window into a…

Performance specified maintenance contracts (PSMC) have been operational in New Zealand for more than six years.

The transverse shear forces generated by multi-axle groups depends on many factors including turn geometry, vehicle type, axle weights, tyre size and configuration, suspension geometry, and the number and type of axles.

Horizontal curves have been recognised as a significant safety issue for many years, a more important factor than road width, vertical clearance or sight distance.

Investigations into the cohesive properties and oxidation resistance of an acid cured, epoxy modified open-graded porous asphalt (OGPA) were undertaken and an associated accelerated loading test carried out at Transit New Zealand’s CAPTIF facility.

In 2006–2007, 35 road-derived sediments (RDS) consisting of street sweepings and catchpit (ie sump) sediments, were collected from three cities in New Zealand; namely Auckland, Hamilton and Christchurch.

The purpose of this research report was to review the use of congestion charging schemes in relation to the urban form of a selection of international cities.

Transit New Zealand Research Report No. 32, Site design for heavy vehicle facilities, is to assist architects and site planners in the design of on-site overall design and spatial arrangements for manoeuvring and parking vehicles.

The primary objective of the project was the development of criteria to define the end-of–life condition of pavements.
