T15 is an aggregate testing specification, its purpose is to standardise the test conditions used in the repeat load triaxial test.

This test procedure covers the determination of the rebound deflection of a pavement under a standard wheel load and tyre pressure, with or without temperature measurements.

M04 Specification for basecourse aggregate and accompanying Notes sets out requirements for basecourse aggregate for use on state highways and other heavily trafficked roadways.

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

T19 specification sets out procedures for determining an optimised blend of aggregate and binders for the stabilisation of pavements.

T19 specification sets out procedures for determining an optimised blend of aggregate and binders for the stabilisation of pavements.

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.

This method can be used to determine the pore size distribution of the openings in a filter fabric by sieving.

This specification applies to the in-situ stabilisation of granular pavement layers using cement, lime, bitumen emulsion or foamed bitumen.

Stabilisation of pavement layers has a long history in New Zealand.
