AS/NZS 2891.14.5:2014 PDF Download

AS/NZS 2891.14.5:2014 is a standard that provides guidelines for conducting field density tests on asphalt. The purpose of this standard is to determine the density ratio and percentage air voids of compacted asphalt in the field. The standard applies to asphalt with a nominal size of up to 40 mm.

The density ratio is a measure of the compactness of the asphalt, calculated by dividing the density of the compacted asphalt by the maximum theoretical density. This ratio indicates the extent to which the asphalt has been properly compacted. On the other hand, the percentage air voids represent the volume of air trapped within the compacted asphalt, indicating the quality of the compaction process.

This standard specifies the sampling and testing methods for determining the density ratio and percentage air voids. It provides detailed instructions on sample collection, preparation, and testing procedures, as well as the required equipment and measurement techniques. Compliance with these testing procedures ensures reliable and consistent results, allowing for accurate assessment of the quality and performance of the asphalt.
