ASTM D1188/D1188M-22 PDF Download

ASTM D1188/D1188M-22 is a standard test method that specifies the procedure for determining the bulk specific gravity of compacted asphalt mixtures using coated samples. The scope of this test method covers specimens of Parafilm-coated asphalt mixtures that may contain open or interconnecting voids, or absorb more than 2.0% of water by volume, or both.

The purpose of this test method is to provide a means of calculating the unit weight of compacted asphalt mixtures based on the bulk specific gravity. It is important to note that this test method should be used in conjunction with Test Method D2726/D2726M, which provides a method for calculating the percent water absorbed by the specimen on a volume basis.

It is also worth mentioning that the standard includes references to notes and footnotes, which provide additional explanatory information. However, these notes and footnotes, excluding those in tables and figures, are not considered as requirements of the standard.
