Flexural beam breakage and fatigue tests were conducted in 2008–11 to determine their relationships with pavement fatigue life and tensile strain for a range of New Zealand materials for use in pavement design of stabilised aggregates.

Research was undertaken in 2009–11 to evaluate the potential benefits of multigrade bitumens in chipsealing in New Zealand.

Friction course surfacing has been used on New Zealand road pavements since the early 1970s.

Premature distress in unbound basecourses has occurred regularly in New Zealand.

The objective of this research, which was carried out between 2006 and 2007, was to propose methods to disseminate and incorporate local as well as international knowledge of OGPA performance into the current New Zealand asset management systems. Com…

Alkali silica reaction (ASR) has, until recently, been considered to present a low risk to concrete in the South Island of New Zealand.

Robust condition data feeding into asset management processes is a key step towards having confidence in long-term strategies for renewals and replacements.

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.

Statistical modelling was undertaken to develop a means for reliably predicting the expected in-service skid resistance of any rural section of the New Zealand state highway network surfaced with chip seal.

The stabilisation of near-surface granular pavement materials is accepted practice in transportation maintenance and capital development projects in Australasia.
