This research, carried out in 2003–2004, aimed to facilitate the recycling of asphalt mix, recycled asphalt pavement (RAP), and crumb rubber (CR) from waste tyres into New Zealand roads.

New Zealand granular pavement design is currently based on the assumption that all deformation of the pavement shape under traffic loading occurs in the subgrade.

This research proposes a new practical method for predicting the performance of unbound granular materials, including alternative, industrial by-products and recycled materials in New Zealand.

New Zealand started a Long-Term Pavement Performance (LTPP) programme on the state highway network during 2000.

Truck Mounted Attenuators (TMA) are widely used on New Zealand Level 2 and 3 state highways and on some network roads that carry high-volume high-speed traffic, to provide safe environments for both roadwork crews and road users.

Reliable techniques have been used in a number of countries throughout the world for some years now for the prediction, measurement, assessment and control of road traffic noise.

This research carried out in Christchurch in 2004 and 2005 looks at the problem of land transport noise in New Zealand and examines the effects of noise, and the options for its reduction.

Research was undertaken during 2004/05 to determine the effect of short approach through-lanes and downstream merges on lane use at signalised intersections, and to find ways of improving use.

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

In 2003, Sport and Recreation New Zealand (SPARC) and the Cancer Society of New Zealand commissioned a major social marketing survey to segment adult New Zealanders in terms of physical activity and healthy eating habits.
