scope:
This Standard sets out the method for determining the following properties of compacted asphalt:
(a) Percentage air voids from separately determined values of bulk density and maximum density.
(b) Absorbed binder, effective binder, maximum theoretical density, voids in the mineral aggregate, and voids filled with binder where the proportions of component materials are known.
NOTE: The relationship between these properties is demonstrated in Appendix A.
Where the air void content of in-situ compacted asphalt is required, for compaction compliance testing, determine the air void content in accordance with AS/NZS 2891.14.5.
NOTE: The air void content can be determined using either this Standard or AS/NZS 2891.14.5. This Standard is intended for laboratory compacted asphalt and field samples of asphalt for investigation. AS/NZS 2891.14.5 is intended where percentage compaction and percentage in-situ air voids are determined for compaction compliance testing.
