The viability of blending high polished stone value (PSV) sealing chips with standard chips in two-coat seals and void fills was investigated, with particular emphasis on their physical performance with respect to abrasion and skid resistance.

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.

In the 21 years from 1987 to 2007 inclusive, 22 children were killed, 45 seriously injured and 91 received minor injuries when crossing the road to or from a school bus.

This database is part of a research project to produce a comprehensive national database of information on trips and parking related to land use in New Zealand since 1990, to identify trends that have occurred since the 1970s, and to compare the New …

Road traffic noise is a major cause of environmental concern in New Zealand.

The objectives of this research project were to produce a comprehensive national database of information on trips and parking related to land use in New Zealand since 1990, to identify trends that have occurred since the 1970s, and to compare the New…

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.

Recent government legislation and policy promotes an increase in walking and cycling as an alternative to the increasing demand for motor vehicle travel.

The objective of this project was to develop and test an apparatus and procedure for determining natural frequency and damping ratio for heavy vehicle suspension systems. A test has been developed that involves supporting an axle group on collapsible…

A new mix design system for porous asphalt based on maximising the effective void content, but maintaining sufficient strength through the use of polymer-modified bitumen, was developed and trialled.
