This specification shall apply to the in-situ stabilisation of subgrade layers comprising either natural in situ soils, imported fill materials or a combination of both using cement, lime or a combination of these.

These notes provide guidance for the engineer to aid in their decision to reject or accept a material proposed for use a basecourse or sub-bases used on state highways and other roadways constructed in accordance with TNZ B/3 performance based specif…

This ethylene glycol accelerated weathering test method (NZTA T20) has been developed to assess the durability of aggregates for pavement construction.

This Q05 specification has been developed to set out the standard processes required by Waka Kotahi so that assurance can be provided that bitumen of acceptable quality is imported into New Zealand and applied to road pavement surfacings.

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.

This specification and guidance notes apply to the construction of subsoil drains which consist of geotextile lined trenches filled with drainage aggregate.

This specification and guidance notes set out the material and construction requirements for geotextiles for use as separation and/or filtration applications in highway earthworks and pavements.

This method can be used to provide a simple quality control test to determine the permeability of a fabric.
