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.

A study, carried out in 1998–2000, investigated if a traffic noise lvel of 55dBA, the level allowed in the 1994 Transit New Zealand Road traffic noise guidelines, was an acceptable limit in New Zealand for areas that previously had low traffic noise.

A methodology has been developed to identify the cost-optimal earthworks cut slope design and establishment of appropriate earthworks contingency factors.

Deck joints are a potential source of deterioration and maintenance problems in a bridge structure and have been identified as the most common maintenance problem in New Zealand road bridges.

While pavement design and management practices are based on static axle loads, the actual loads applied to pavements are dynamic, varying as the suspension responds to the unevenness in the pavement surface.

This rule specifies the legal requirements for the design and construction of all passenger service vehicles in New Zealand.

The vehicle-ownership forecasting model research project, undertaken in 1996–1997, is described.

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