This project aimed to assist the development of understandable, cost-effective static signage to warn drivers of the potential for lower skid resistance in areas renowned for periodic slippery conditions.

This paper develops a methodology and evidence to enable the assessment of wider economic impacts of transport.

Research undertaken between 2007 and 2009 examined the influence of binder rise in reducing tyre–road friction of chipseal surfaces.

The objective of this project was to investigate the durability and mechanical integrity of aggregate with a high polished stone value (>60) used in hot mix asphalt, particularly chips or coarse aggregates in stone-on-stone mixes such as stone mas…

This report details the findings from research conducted on the Long-Term Pavement Performance Programme (LTPP) and on the Transit New Zealand CAPTIF programme for accelerated pavement testing.

A review of international literature covering the use of fibre reinforcement in cohesive and non-cohesive soils as a means of strengthening these materials was begun in 1992.

The Austroads pavement design guide is currently used in New Zealand for pavement design.

A pavement design model developed in the USA is used to estimate the equilibrium degree of saturation in pavement subgrade and basecourse materials.

This project, undertaken in 1992, simulated the situation when a bridge is widened with a new concrete extension and then, after a delay period, traffic continues to use the existing old concrete bridge while the extension is curing.

Profile variance, which is already listed in the NZ Transport Agency's RAMM database, is a measure of the difference between the actual road profile and its moving average over selected moving average lengths.
