This report describes a New Zealand study of the effect of different binders on the rate of chipseal texture loss under traffic.

Freight transportation is one of the key but often overlooked areas of transport policy.

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.

Roughness indices are used to monitor road condition and prioritise maintenance and rehabilitation programs. The most commonly used measure in New Zealand is NAASRA roughness which is based on the dynamic response of a normal passenger car.

The accumulation of chipseal layers following repeated road resurfacing frequently results in an unstable surface that can flush quickly, sometimes within twelve months.
