NEW NZS 4407 - ONE ROAD AGGREGATE STANDARD TO UNITE THEM ALL
The old Standard NZS 4407 - Methods Of Sampling And Testing Road Aggregates, had 24 separate parts, each of which was essentially a separate test method for road aggregates, for example;
- NZS 4407.3.10: 1991 - Methods of sampling and testing road aggregates - Methods of testing road aggregates - Laboratory tests - Test 3.10 The crushing resistance of coarse aggregate under a specific load
The new NZS 4407: 2015 - Methods Of Sampling And Testing Road Aggregates, is now a single Standard and has amalgamated all the parts into this one Standard. Basically each of the separate test methods now, more or less, forms a sub-section in the new Standard, and conveniently most of the test method numbers are the same as the sub-section numbers.
The following Masterspec sections have been upgraded to reflect this change:
8226 GRAVEL & STONE PAVING (in Landscapes, Structural & Civil)
8612 BULK EARTHWORKS DEVELOPMENT (in Structural & Civil)
8631 SUB-BASECOURSE & BASECOURSE CONSTRUCTION (in Structural & Civil)
