ASTM D5100

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.

1. 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 SI units are to be regarded as the standard. The values given in parentheses are for information only.

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.
