Scope1.1 This specification covers the quality and grading ofcrushed stone, crushed slag, and water-worn gravel suitable foruse as coarse mineral aggregate on built-up roofs.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as stand
4、ard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.2. Referenced Documents2.1 ASTM Standards:2C29/C29M Test Method for Bulk Density (“Un
