ASTM D2041/D2041M-19 PDF Download

The ASTM D2041/D2041M-19 standard is a test method used to determine the theoretical maximum specific gravity and density of asphalt mixtures. These properties are influenced by the composition of the mixture, including the types and amounts of aggregates, asphalt binder, and other materials present.

The maximum specific gravity is important for various calculations and purposes. It is used to calculate the air voids in the compacted asphalt mixture, determine the amount of asphalt binder absorbed by the aggregate, and provide target values for the compaction of asphalt mixtures.

The standard emphasizes that reliable results depend on the competence of the personnel performing the procedure and the calibration and maintenance of the equipment used. Compliance with specifications alone does not ensure reliable results, but following the suggested guidelines provides a means of evaluating and controlling various factors.

The test method specifically covers the determination of theoretical maximum specific gravity and density of uncompacted asphalt mixtures at a temperature of 25°C (77°F). It provides measurements in both SI units and nonstandard units for residual pressure, but volume and mass measurements are given only in SI units.

Notes and footnotes in the standard provide additional explanatory material, but these should not be considered as requirements of the standard.
