Which standard is referenced for the test method for bulk specific gravity and density of non-absorptive compacted bituminous mixtures?

The standard referenced for the test method for bulk specific gravity and density of non-absorptive compacted bituminous mixtures is ASTM D2726. This standard is specifically designed to provide a testing procedure that accurately determines the bulk specific gravity and density of compacted asphalt mixtures that do not absorb significant amounts of water.

Understanding the significance of this method is key: it allows for the evaluation of the volumetric properties of asphalt mixtures, which are crucial for determining the quality and performance of the asphalt in various applications, particularly in pavement construction. The absorption characteristics of the mixture are important to consider, as they influence how materials perform under traffic loading and environmental conditions.

In summary, ASTM D2726 is the appropriate standard because it focuses on the specific properties needed for evaluating non-absorptive compacted bituminous mixtures.
