AS/NZS 2891.3.2:2013 standard provides guidelines for determining the binder content and aggregate grading of asphalt mixes using the centrifugal extraction method. This method involves extracting the binder from the mix and analyzing the particle size distribution of the aggregate through sieve analysis.

The standard highlights that this method may not be suitable for mixes composed of highly absorptive aggregates, indicating that other methods should be considered in such cases. The purpose of this standard is to ensure accurate and reliable measurements of binder content and aggregate grading in asphalt mixes. Adhering to this standard helps to ensure the quality and consistency of asphalt mixes, supporting the construction and maintenance of durable and safe road surfaces.
