Flushed and unflushed chipseal samples were taken in 1997–98, near sites where flushing had occurred on state highways in the Wairarapa, New Zealand.

Melter slag is a major by-product of the steel manufacturing process, and its potential for use as an aggregate in open-graded emulsion mixes (OGEMs), is the topic of this report.

The reproducibility and repeatability of the sand circle test for measuring texture depth in pavement surfaces was compared with a new test using wallpaper size and a flexible perspex plate covered by a rubber pad.

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.

A literature review was carried out in 1993 on the potential use of crumb-sized ground tyre rubber (GTR), obtained from recycling waste tyres, as an additive to bitumen used in constructing New Zealand pavements.

Geotextiles are permeable textile fabrics used in engineering applications.

This research project investigated the differences in cohesive energies of model chipseal samples prepared from bitumen emulsions, the base binders, and the kerosene cutback base binder.

This project was designed to investigate the importance of drainage maintenance for pavement performance and to recommend a maintenance strategy.
