Bridge health monitoring is a method of evaluating the ability of a bridge to perform its required task (also called fitness for purpose) by monitoring the response of the bridge to the traffic loads it has to withstand.

Small diameter tyres are increasingly being used in heavy vehicle applications.

A high binder content (78%) polymer-modified bitumen emulsion used in a 'racked-in' sealing system was trialed from 1993 to 1995 as a surfacing in high traffic stress areas for New Zealand roads.

Obtaining a reference road profile is vital for the validation of profiling devices.

A computer simulation study was conducted to investigate the viability of harmonising rut depth measurements from different automated rut depth measurement profilometers.

Geosynthetic-reinforced soils (GRS have been found to be cost-effective compared to traditionally used retaining structures in specific situations.

This research report presents a literature review on the topic of long-life pavements and provides details of an assessment of heavy duty structural asphalt pavements in New Zealand, carried out in 2001-2002.

The historical development of the traditional Marshall and the modern gyratory-based, performance-related asphalt mix design procedures is described.

To improve the efficiency of the road transport industry in New Zealand, a range of mass limit increases for heavy vehicles has been proposed.

The objective of this project, carried out in 2001, was to investigate the design of an operational scale device for testing the 'road-friendliness' of heavy vehicle suspensions.
