The design of frost-resistant pavements are discussed.

The objective of this research (undertaken in 2010–12) was to provide improved evidence (potentially leading to improved modelling, monitoring and evaluation methods) on the implications of major road investments in New Zealand on significant factors…

This research report on the strategic electronic monitoring of heavy commercial vehicles (HCVs) was prepared by Traffic Design Group in 2011–12.

In New Zealand, premature failure of low volume, low strength state highways and local authority roads has sometimes occurred due to significant changes in heavy commercial vehicle traffic.

Areas of New Zealand are running out of premium aggregates that meet the demanding specifications used in unbound granular road construction.

Customers for long-distance goods haulage are free to decide on which transport modes to use on the basis of price and performance.

An efficient transport system is crucial for the New Zealand economy.

This study assessed the feasibility and materiality of allowing for real-price changes in economic appraisals over the course of a transport project's appraisal period.

The objective of this research, undertaken in 2008–11, was the development of an improved method of modelling the decision to rehabilitate a typical New Zealand thin-surfaced unbound granular pavement.

This report presents the results of a first attempt to combine detailed road geometry, road surface condition, carriageway characteristics and crash data information to develop a statistical crash prediction model for application to rural New Zealand…
