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.

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 was undertaken in 1997–98 to prepare two sets of provisional environmental guidelines for roading contractors carrying out road works in New Zealand.

The guidelines for sensitivity analysis in project evaluation, as used in the Transit New Zealand Project Evaluation Manual (PEM), have been improved.

The application of the Austroads Pavement design guide to Taranaki 'brown ash' has been investigated.

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

An evaluation of models which predict noise levels from road traffic in terms of the LEQ (24-hour) index was undertaken in 1998 by comparing predicted levels with noise levels measured at 20 sites.

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.
