The purpose of this research was to identify the barriers to using tyre-derived crumb rubber in bitumen binder in New Zealand roading and the methods to remove these barriers to create market demand for New Zealand waste tyre-derived products.

This report details research carried out from 2012 to 2015 into chipseal flushing.

The application of geosynthetics (ie geogrids) for the stabilisation of basecourses prepared with a River Run rounded gravel aggregate was investigated.

A review has been made of the international literature that was available up to 1996 and of New Zealand experience and practices for the stabilisation of materials for use in road pavements.

A complete road profile ranges from large scale topographic features to microscopic asperities on the surface of aggregates.

New Zealand's road network uses pavement types of widely differing properties, ranging from very smooth asphaltic concrete to coarse chipseal surfaces having macrotexture levels not often found elsewhere in the world.

Responses to a discussion document on the development of the Road Assessment and Maintenance Management (RAMM) system, issued by Transit New Zealand in 1995, are summarised.

The objectives of this study were to investigate the relationship between permeability of chipseals, waterfilm thickness, basecourse moisture sensitivity, heavy traffic volumes, and premature pavement failure following construction through the use of…

The research investigated aspects of the use of epoxy modified bitumen for construction of chip seals.

Road bridges are subjected to millions of cycles of heavy vehicle loading over their design lives, and the introduction of higher vehicle mass limits on New Zealand roads will significantly increase the rates of fatigue damage in bridge superstructur…
