The specification covers the manufacture of the Hi-Lab materials, and construction of Hi-Lab structural pavements. Hi-Lab is used for heavy duty pavements. The pavement structure consists of a very densely packed and interlocked, mainly single sized large aggregate skeleton, combined with a low cement and fines void filler. Hi-Lab can be used for new construction or rehabilitation overlays.

Q/3 normal QA level contract specification covers the quality assurance requirements for contracts which have been assessed at the normal quality assurance level. Q/4 high QA level contract covers the quality assurance requirements for contracts which have been assessed at the high quality assurance level. Both specifications should be applied to all contracts on state highways which involve road construction, road maintenance and structures. The guideline notes covers the roles of the client, consultant and contractor in the application of quality assurance provisions in roading contracts.

Guidelines for pavement specifications for primary cycling routes including cycle lanes and cycle paths, shared paths and separated cycleways, as well as pavement shoulders where cycling demand is high and where a high level of service is desired. For a secondary or minor route in a cycling network, a lower level specification may be appropriate.

This ethylene glycol accelerated weathering test method (NZTA T20) has been developed to assess the durability of aggregates for pavement construction.
It is based on elements of NZS 4407 Test 3.10 (The Crushing Resistance of Coarse Aggregate under a Specified Load) and AS 1141.22 (Methods for sampling and testing aggregates - Wet/Dry strength variation).
The method also uses laboratory equipment and methods described in other parts of NZS 4407 so users are advised to read this method in conjunction with NZS 4407.

The T28 laboratory test method is used to determine the maximum dry density and optimum water content for aggregates used in pavement construction. The test procedure provides an essential criterion for the management of quality for granular pavement construction, i.e. the maximum dry density.
