Leutner shear tests to measure bond strength and flexural beam tests to measure flexibility were conducted on specialist surfacing resins used in New Zealand for coloured and high-friction surfacings.

The design of frost-resistant pavements are discussed.

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.

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.

Statistical modelling was undertaken to develop a means for reliably predicting the expected in-service skid resistance of any rural section of the New Zealand state highway network surfaced with chip seal.

The stabilisation of near-surface granular pavement materials is accepted practice in transportation maintenance and capital development projects in Australasia.

In April 1994 a comparative trial of the performance of bitumen emulsion and cutback bitumen as chipsealing binders was constructed.

This report describes a substantial research project to determine procedures for assessing the road-friendliness of heavy vehicle suspension systems. The initial aim was to develop a procedure for replicating the on-road dynamic wheel forces generate…

This report presents the results of a research project, carried out in 1994, to investigate the suitability of fixed slip friction meters for on-road determination of pavement surface abrasiveness of New Zealand SEALED roads.
