ASTM D1188-07
(Test Method)Standard Test Method for Bulk Specific Gravity and Density of Compacted Bituminous Mixtures Using Coated Samples
Standard Test Method for Bulk Specific Gravity and Density of Compacted Bituminous Mixtures Using Coated Samples
SIGNIFICANCE AND USE
This test method is useful in calculating percent air voids as given in Test Method D 3203. Since specific gravity has no units, it must be converted to density when this type of measurement is required. This conversion is made by multiplying the specific gravity at a given temperature by the density of water at the same temperature.
SCOPE
1.1 This test method covers the determination of bulk specific gravity of specimens of Parafilm-coated, compacted bituminous mixtures as defined in Terminology E 12.
1.2 This method should be used with samples that contain open or interconnecting voids or absorb more than 2 % of water by volume, or both, as determined by Section 8.
1.3 The bulk specific gravity of the compacted bituminous mixtures may be used in calculating the unit weight of the mixture.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
