0

Source: ASTM International

This specification covers the standards for the quality and grading of crushed stone, crushed slag, and water-worn gravel intended for use as coarse mineral aggregate on built-up roofs. The crushed stone and gravel shall be hard, durable, opaque, and free of foreign substances. The crushed slag, on the other hand, shall be hard, air-cooled, and free of as well of any foreign particles. The specimens shall comply with the gradation and physical requirements prescribed herein and shall undergo testing which include a gradation test, moisture test, unit mass test, dust, and hardness test.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers the quality and grading of crushed stone, crushed slag, and water-worn gravel suitable for use as coarse mineral aggregate on built-up roofs.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
