AS 2758.2:2021 pdf download.Aggregates and rock for engineering purposes Part 2: Specification for sealing aggregate.

Unless it is practical to supply different classes of aggregate to the same project, specifiers should determine the required

aggregate class based on the most severe requirements for any road to be sealed under works specification.

The works specification should also consider the type of vehicles when nominating any aggregate classification.

5 Sampling

Where lot testing is referenced in Tables 1,2, 3 and 4, a lot shall consist of not less than 5 samples.

Sampling of an aggregate shall be carried out in accordance with one of the methods described in AS 1141.3.1.

NOTE 1 The frequency of sampling should be nominated in the works specification or the supply agreement or as agreed with the

supplier. In the absence of any of these documents, refer to AS 2758.0:2020 Appendix A for a sampling scheme.

NOTE 2 Reference samples may be taken during the course of supply and retained for later testing.
