High moisture within pavements accelerates pavement deterioration.

The purpose of this research was to isolate and identify the reasons why some reseals have very long lives, and to identify which of these factors could economically be applied to reseals in future contracts, thus leading to a reduction in whole-of-l…

This research project aimed to provide an analysis of the suitability of existing benchmarking methodologies for use in the roading sector in New Zealand.

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.

There are approximately 270 bridges on New Zealand’s state highway network and many more bridges on local roads with steel concrete composite superstructures.

The objective of this research, carried out between 2012 and 2015, was to improve the treatment selection algorithm (TSA).

Specialist surfacings such as high-friction and coloured traffic-calming surfaces have gained huge popularity since their introduction.

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.
