AS/NZS 2891.7.3:2014 PDF Download

AS/NZS 2891.7.3:2014 is a standard that provides guidelines for determining the maximum density of asphalt using a method called methylated spirits displacement. The purpose of this standard is to establish a standardized procedure for accurately measuring the density of voidless asphalt.

The method outlined in this standard involves displacing methylated spirits with the compacted asphalt sample. By calculating the difference in volume before and after displacement, the maximum density can be determined. This process ensures that the density measurement is precise and consistent across different asphalt samples.

By using methylated spirits, this standard ensures a reliable and readily available displacement fluid. The method also takes into account any variations in temperature and pressure to ensure accurate measurements. The maximum density determination is important for understanding the quality and performance of asphalt materials, as it affects factors such as strength, durability, and resistance to deformation.
