Foamed bitumen stabilisation is gaining wide acceptance internationally for pavement stabilisation, but has not been practised in New Zealand.

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

This report describes the results of the project commissioned to investigate the effects of trench patches and service covers on pavement management.

Obtaining a reference road profile is vital for the validation of profiling devices.

A computer simulation study was conducted to investigate the viability of harmonising rut depth measurements from different automated rut depth measurement profilometers.

This research was carried out between 2003 and 2005 at Opus International Consultants, Central Laboratories, Lower Hutt.

Geosynthetic-reinforced soils (GRS have been found to be cost-effective compared to traditionally used retaining structures in specific situations.

The risk involved in pavement design is that the pavement life will be shorter than the design life.

Eight hollow-core precast-prestressed concrete beams were removed and recovered in good condition from the Pahurehure Inlet Bridge No. 2 on the Auckland Southern Motorway, New Zealand, in 1988.

This report describes research in 2004 and 2005 aimed at improving the means by which the durability of bitumens manufactured or imported to New Zealand for use in chipseals is assessed and monitored.
