Standard Test Method for Determining the Adherent Coating on Coarse Aggregates (Withdrawn 2012)
This test method assigns a measurable value to the amount of fine material adhering to the aggregate.
1.1 This test method is used to determine the adherent coating on coarse aggregate (aggregate retained on the 2.36-mm (No. 8) sieve) for the following purposes:
1.1.1 Preliminary investigation of mineral aggregate sources.
1.1.2 Control of mineral aggregates used in hot mix asphalt (HMA) pavements, seal coats, cover coats, surface treatments, cold mix asphalt, and portland cement concrete at the source of supply.
1.1.3 Control of mineral aggregate processing requirements.
1.1.4 Acceptance or rejection of aggregates based on adherent coating.
1.2 The values shown in SI units are to be regarded as 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.
Note 1—This test method is modeled after Federal Land Highways T 512-94.
