AS/NZS 2891.14.1.1:2013 PDF Download

AS/NZS 2891.14.1.1:2013 standard provides guidelines on how to determine the field density of compacted asphalt using a nuclear surface moisture-density gauge in the direct transmission mode. This method is suitable for asphalt layers with a thickness of at least 75 mm and a nominal maximum size of 40 mm.

It is important to note that the standard does not provide specific instructions on how to operate the gauge itself, as this information is typically provided by the manufacturer in their handbook. The use of a nuclear gauge allows for an indirect measure of the field density, which necessitates calibration in accordance with AS 1289.5.8.4. Additionally, regular checks on both the operation and calibration of the gauge are required to ensure accurate results.
