A study of cores from multilayer chipseals shows that fine solid materials (passing 4.75 mm) fill a significant proportion of the chipseal volume that would otherwise be available for bitumen.

This report presents the findings of research investigating the opportunities and barriers to promoting sustainability in New Zealand’s rail system.

As part of the management of the land transport system of New Zealand, a study of land transport pricing policies, with particular emphasis on road pricing, has been carried out.

A research project was undertaken to appraise international evidence on the effects of changes in urban public transport systems and services on the extent of switching to/from car travel and on total road traffic volumes, and to develop guidelines f…

This report describes work to investigate sealing aggregate bonding to standard and polymer modified bituminous binders.

This project was undertaken to establish reliable test methods by which the performance of road markings in New Zealand can be assessed.

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.

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

The report provides a literature review and research plan describing where further research is needed to quantify or value external effects, otherwise known as externalities, from the land transport system.

Potential economic disbenefits of dust emission from unsealed roads impact on crop production, animal food supply and health, accident potential, property values and maintenance costs, vehicle operating costs and personal health.
