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

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

This report details the findings from research conducted on the Long-Term Pavement Performance Programme (LTPP) and on the Transit New Zealand CAPTIF programme for accelerated pavement testing.

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.

Accelerated pavement testing at CAPTIF (Canterbury Accelerated Pavement Testing Indoor Facility, Christchurch, New Zealand) was conducted between 2000 and 2004 on a standard two-coat chipseal that is typically used on New Zealand roads.

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).

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

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…
