AS/NZS 2891.3.3:2013, also known as the "Methods of Sampling and Testing Asphalt - Binder Content and Aggregate Grading - Pressure Filter Method," provides guidelines on how to determine the binder content and particle size distribution of asphalt mixes using a pressure filtering technique. This standard is applicable to mixes that contain a bituminous binder and aims to ensure accurate and consistent results.

The standard outlines the step-by-step procedure for determining the binder content of asphalt mixes. This is done by subjecting a sample of the mix to pressure filtering, which separates the binder from the aggregate. The binder content is then calculated based on the weight difference before and after filtering.

Additionally, the standard provides instructions for analyzing the particle size distribution of the aggregate in the asphalt mix. This is achieved through sieve analysis, which involves passing the aggregate through a series of sieves of different sizes and measuring the weight retained on each sieve. The results of this analysis help determine the grading of the aggregate.
