This report presents a road geometry survey of the New Zealand highway system and the subsequent use of the data to model the relationship between highway features and relative crash risk.

The report presents a definition of the scope and coverage of an ideal manual for the design of roading structures to meet the needs of Transit New Zealand and compares the present Transit New Zealand Bridge Manual and the 1992 Austroads Bridge Desig…

The British Pendulum Tester (BPT) is used to assess the skid resistance of road surfaces.

This study investigates the cost effectiveness of conventional and alternative construction and maintenance procedures for unsealed roadways.

Aternatives to automotive gas oil (AGO) used to flux (soften) bitumen used in chipsealing have been investigated.

One hundred and thirty participants (70 males, 60 females), aged between 18 and 40, took part in this research to test the relative conspicuity of eight different test-garments.

Most New Zealand pavements comprise a granular base with a thin bituminous surfacing.

This paper reports an assessment of skills gaps and training needs likely in 2035 for New Zealand, resulting from the technological change from implementation of intelligent transport systems (ITS) in land transport.

This report details a framework for rationally arriving at economically justifiable operating speed reductions to compensate for the inability to achieve recommended levels of skid resistance on high-risk curves.

There is anecdotal evidence that pavement maintenance patches fail within a few years and research was undertaken to develop a framework for predicting the life of patches to enable asset managers to choose the right treatment to give the life requir…
