AS/NZS 2891.2.2:2014 PDF Download

AS/NZS 2891.2.2:2014 is a standard that outlines the methods for sampling and testing asphalt, specifically focusing on the sample preparation process. The standard provides guidance on how to compact asphalt test specimens using a gyratory compactor.

The purpose of this standard is to ensure consistent and accurate compaction of asphalt specimens, which is crucial for obtaining reliable and representative testing results. The gyratory compactor is a specialized machine that applies both vertical and horizontal pressures on the asphalt specimen, simulating the compaction process that occurs during actual pavement construction.

The standard specifies the requirements for the compaction process, including the equipment and test specimen preparation. It provides detailed instructions on how to set up the gyratory compactor, adjust the variables such as the speed and pressure, and perform the compaction process.
