New Zealand pavement engineers, in collaboration with colleagues in South Africa and Australia, are recognised internationally as leaders in the use of stabilisation in highway, road, airport, port and industrial hardstand pavement applications.

A review of the performance of slopes in historical earthquakes, a review of relevant literature describing recent research, consideration of New Zealand’s distinctive topography and seismicity, and limited numerical analyses have been carried out.

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…

High moisture within pavements accelerates pavement deterioration.

Providing a safe, comfortable, cost-effective visual environment to help drivers navigate rural roads requires a better understanding of the strengths and limitations of different delineation devices, materials and treatment configurations.

This research considered maintenance of the audio, tactile and visual effects of ATP roadmarkings including for situations where the road surface was to be resealed while the ATP roadmarkings had remaining effective life.

The application of geosynthetics (ie geogrids) for the stabilisation of basecourses prepared with a River Run rounded gravel aggregate was investigated.

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

This report details research carried out from 2012 to 2015 into chipseal flushing.

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