Scope

1.1 This test method determines the adhesion of mineral aggregate when applied over a pour coat of hot bitumen on a roof membrane.

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.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Significance and Use

The quantities of mineral aggregate adhered to the surface of a roof vary with the characteristics and total amount of the aggregate. Mineral aggregate shields bituminous membranes from solar radiation. Unadhered mineral aggregate can be displaced by wind, water, and traffic, exposing the bitumen.

This test method provides a laboratory means of determining and recording the mass of aggregate that adheres to a bituminous pour coat.
