This practice simulates the polishing action of vehicular traffic on coarse aggregates used in bituminous pavements.

A polish value is determined that may be used to rate or classify coarse aggregates for their ability to resist polishing under traffic.

1. Scope

1.1 This practice covers a laboratory procedure by which an estimate may be made of the extent to which different coarse aggregates may polish.

1.2 The values stated in inch-pound units are to be regarded as the standard.

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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
