Subgrade stabilisation is a common road construction practice in New Zealand.

Transit New Zealand regional offices and selected local authorities were asked for information from their records on age and proximity to the coast of their bridges.

This report presents the results of a literature review carried out in 1996.

A study of cores from multilayer chipseals shows that fine solid materials (passing 4.75 mm) fill a significant proportion of the chipseal volume that would otherwise be available for bitumen.

Hollow core units for bridge spans of various length.

The objective of this project was to investigate the practicality of adopting the AS 5100 bridge design standard for New Zealand.

In recent years, the standard practice in New Zealand regarding binder selection for state highways has been to use harder penetration grade binders and reduced diluents, after some research indicated that the use of harder binders slowed the onset o…

To enable the improvement of the modelling of pavement response and performance, the measurement of full-scale tyre surface contact stress distributions in all three of the coordinate directions was undertaken.

New Zealand granular pavement design is currently based on the assumption that all deformation of the pavement shape under traffic loading occurs in the subgrade.

This research proposes a new practical method for predicting the performance of unbound granular materials, including alternative, industrial by-products and recycled materials in New Zealand.
