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.

Speed is a major contributing factor in fatal and serious crashes in the rural environment (35% of fatal and 28% of serious crashes in 2003).

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.

The study undertaken in 1992 identified the factors that contribute to the costs of operating vehicles on unsealed roads compared to those costs on sealed roads in New Zealand.

This report presents the findings of the second stage of research looking at regional transport modelling and long-term road planning.

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.
