Methods of Sampling and Testing Road Aggregates
Also Known As:
NZS 4407:2015 is a standard that provides detailed test methods and procedures for sampling and testing road aggregates. The main objective of this standard is to ensure that the aggregates used in road pavement construction are compliant and fit for purpose. Testing agencies that adhere to this standard will be able to demonstrate to stakeholders, such as road constructors and government authorities, that the aggregates meet the necessary quality requirements.
The standard covers various aspects of aggregate testing, including sampling procedures, physical properties, mechanical properties, and chemical properties. It outlines specific test methods for determining the characteristics of the aggregates, such as particle size distribution, flakiness index, Los Angeles abrasion resistance, and soundness. These tests are crucial for evaluating the performance and durability of road aggregates.
