Aggregates used as base materials in thin-surfaced granular pavements common to New Zealand contribute at least half the wheeltrack rutting and roughness seen at the surface.

This report describes the results of a project to investigate the quality of road survey data collected from road networks in New Zealand.

Structural hot mix asphalt (HMA) pavements have become popular in New Zealand in recent times as heavy traffic volumes have increased and early failures of granular pavements have become more common, especially in urban areas where road maintenance c…

This digest summarises the findings of two reports prepared as part of Transit New Zealand's transport pricing study, excluding recommendations for further research which are the subject of another document.

In New Zealand excessive deformation in the wheel paths due to post construction densification has occurred in a number of new pavements constructed in recent years.

Dipentene (a solvent derived from radiata pine) and toluene were investigated as alternatives to the ozone-depleting methyl chloroform used in bitumen content determinations of asphalt.
