Published:
Category: Activity management , CAPTIF , Research programme , Research & reports | Audience: General

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

Research Report 198 Comparison of accelerated pavement test facilities in New Zealand and Australia

Published:
Category: Activity management , CAPTIF , Research programme , Research & reports | Audience: General

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).

Research Report 280 Effect on pavement wear of increased mass limits for heavy vehicles – stage 4

Published:
Category: Activity management , CAPTIF , Research programme , Research & reports | Audience: General

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.

Research Report 335 Performance tests for road aggregates and alternative materials

Published:
Category: Activity management , CAPTIF , Research programme , Research & reports | Audience: General

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.

Published:
Category: Activity management , CAPTIF , Research programme , Research & reports | Audience: General

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.

Research Report 084 Replication of VTI's stationary laser profilometer for measuring road surface profiles

Published:
Category: CAPTIF , Research & reports

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

Research Report 463 Development of tensile fatigue criteria for bound materials

Published:
Category: Activity management , CAPTIF , Research programme , Research & reports | Audience: General

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.

Research Report 564 Effects of water on chipseal and basecourse on high-volume roads

Published:
Category: Activity management , CAPTIF , Research programme , Research & reports | Audiences: Road traffic engineers & consultants, Roading contractors

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…
