Significance and Use

The amount and size distribution of noncarbonate (insoluble) material in carbonate aggregates is of interest to those conducting research on the polish susceptibility of stone used in pavements or on the friction properties of pavement surfaces. In addition, some agencies utilize the test for acceptance purposes to delineate carbonate aggregates that polish excessively and become slippery and those that will not.

Note 1The quality of the results produced by this standard are dependent upon the competence of the personnel performing the procedure and the capability, calibration, and the maintenance of the equipment used. Agencies that meet the criteria of Practice D 3666 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D 3666 alone does not completely assure reliable results. Reliable results depend on many factors: following the suggestions of Practice D 3666 or similar acceptable guideline provides a means of evaluating and controlling some of those factors.

1. Scope

1.1 This test method covers determination of the percentage of insoluble residue in carbonate aggregates using hydrochloric acid solution to react the carbonates.

1.2 The values stated in SI units are to be regarded as standard. Regarding sieves, per Specification E 11 , The values stated in SI units shall be considered standard for the dimensions of the wire cloth openings and the diameter of the wires used in the wire cloth. The values stated in inch-pound units shall be considered standard with regard to the sieve frames. When sieve mesh sizes are referenced, the alternate inch-pound designations are provided for information purposes and enclosed in parentheses.

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. Specific precaution statements are given in Section 7.

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