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…

This report details research carried out from 2016 to 2017 as the preparatory stage of a larger programme to understand how chipseals may be improved to withstand increases in horizontal shear forces imposed by traffic loadings.

A comprehensive statistical analysis and review of the dataset was undertaken on the March 2015 LTPP database, including application of transformations on the skewed raw data.

The Transport Agency commissioned Navigatus Consulting to undertake this research project to identify and provide evidence-based recommendations for managing priority safety risks for New Zealand rail operations.

This research reviewed the New Zealand vibrating hammer laboratory compaction test and energy standardisation thereof.
