Foamed bitumen stabilisation is gaining wide acceptance internationally for pavement stabilisation, but has not been practised in New Zealand.

This report describes the results of the project commissioned to investigate the effects of trench patches and service covers on pavement management.

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.

This report describes the results of a project, carried out in 2000–01, to investigate the enhancements carried out to road deterioration (RD) and works effects (WE) models included in the predictive pavement modelling system, HDM-4, with respect to …
