Flexural beam breakage and fatigue tests were conducted in 2008–11 to determine their relationships with pavement fatigue life and tensile strain for a range of New Zealand materials for use in pavement design of stabilised aggregates.

The development and testing, during 1996, of a portable stationary laser profilometer and the associated analysis software is described.

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…

Areas of New Zealand are running out of premium aggregates that meet the demanding specifications used in unbound granular road construction.

This report presents the findings from a review of the operation and completed projects conducted at the Canterbury Accelerated Pavement Testing Indoor Facility (CAPTIF) and the Australian Accelerated Loading Facility (ALF).

In New Zealand heavy vehicles are charged for using the road based on the damage caused passing over the road.

To improve the efficiency of the road transport industry in New Zealand, a range of mass limit increases for heavy vehicles has been proposed.

Internationally low noise porous asphalts are typically laid on top of structural asphalt layers.

The road transport industry in New Zealand has been lobbying for increases in the allowable mass limits for heavy vehicles on the basis that this would give increased efficiency and benefits to the economy.
