Phạm vi áp dụng / Scope of standard

This test method covers the determination of the theoretical maximum specific gravity/gravity mix maximum (G_mm) and density of uncompacted asphalt mixture at 25°C (77°F).

Note 1-The precision of the method is best when the procedure is performed on samples that contain aggregates that are completely coated. In order to assure complete coating, it is desirable to perform the method on samples that are close to the optimum asphalt binder content.

The values stated in SI units are to be regarded as the standard.
