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.

Following an earthquake on 18 June 1994, a large slip partially blocked the Bealey River in Arthur's Pass National Park, South Island, New Zealand, and introduced a large quantity of silt and terrestrial organic matter into the river.

The measurement of traffic volumes on an extensive nationwide road network is a very large task.

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.

A review of the values of travel time savings used for the evaluation of road projects in New Zealand and incorporated in the 1991 Transit New Zealand Project Evaluation Manual was undertaken, largely in 1992.

NETSIM, a very detailed computer model for traffic simulation developed in the United States, is validated and calibrated for use in urban street networks in New Zealand conditions.

Two aspects of hydraulic design are addressed: the determination of a design peak flood flow rate; and the estimation of channel flow resistance.

This report records part of a research programme on tourism benefits from sealing unsealed roads to address concerns raised that the Transit New Zealand project evaluation procedures may not fully account for benefits arising from improving roads in …
