This research continues recent work to investigate ways of analysing and providing for improved passing opportunities on state highways in New Zealand.

One 1986 and three 1991 180/200 penetration grade Safaniya bitumens (from Saudi Arabia) produced by the Marsden Point Refinery were analysed by a range of procedures to detect any significant differences in chemical composition.

A robust methodology has been developed, in 2000–2001, to locate change points (i.e.

Road networks are lifelines for the community and are essential for the economic well-being of New Zealand.

The objective of this project, carried out in 2000–2001, was to study the weathering quality index (WQI), the measure used in the Transit New Zealand M/4:1999 specification basecourse aggregate, in order to determine the changes occurring when a marg…

An accelerated pavement test was conducted at CAPTIF (Canterbury Accelerated Pavement Testing Indoor Facility), Christchurch, New Zealand, between 1999 and 2001, for the purpose of validating the use of the repeat load tri-axial (RLT) apparatus.

The Canterbury Accelerated Pavement Testing Indoor Facility (CAPTIF) is a state-of-the-art pavement testing facility located at Christchurch, New Zealand.

Pavements constructed on volcanic soils behave differently to non-volcanic soils and have higher deflections when dynamically loaded.

This report describes the results of a project to investigate sensitivity of the input parameters used for NZ dTIMS system.

This project examines the costs and benefits of, and alternatives to, the resource consent process of the Resource Management Act 1991 in circumstances where the process has been applied to routine maintenance works on New Zealand state highways.
