The requirements of the 2002 Local Government Act have led to a greater emphasis on local authorities having a holistic approach to risk management.

The aim of the Bike Now research project was to explore specific actions that could be undertaken in the workplace to encourage people to take up (and continue) cycling to work.

The object of this study was to gather data on the levels of bitumen oxidation found in dense asphalt surfacings.

There have been a number of high-profile early failures in New Zealand pavements (rut depths greater than 20mm observed early in the pavement life) associated with ‘greenfield’ pavements (pavements not subjected to traffic during construction).

Investigations into the cohesive properties and oxidation resistance of an acid-cured, epoxy-modified open-graded porous asphalt (EMOGPA) were undertaken, and an associated field trial constructed on State Highway 1 in Christchurch in December 2007.

We updated our earlier study of older people’s travel patterns using the 1997/98 New Zealand Household Travel Survey (NZHTS) with a comparative analysis using the recently compiled 2004–07 Ongoing NZHTS database (ONZHTS).

A 2004 trial of the Otta seal technique in various locations in New Zealand showed that it may be a better option for dust minimisation and, based on life cycle costing, could be a lower-cost option when compared with traditional short-term dust pall…

Dynamic numerical modelling has been carried out in 2005–2007 to investigate the seismic performance of an 11.66 m span, 7.29 m rise, high profile arch culvert.

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.
