Значение и использование

5.1 The test has been widely used as an indicator of the relative quality or competence of various sources of aggregate having similar mineral compositions. The results do not automatically permit valid comparisons to be made between sources distinctly different in origin, composition, or structure. Assign specification limits with extreme care in consideration of available aggregate types and their performance history in specific end uses.

Область применения

1.1 This test method covers testing sizes of coarse aggregate larger than 19 mm (3/4 in.) for resistance to degradation using the Los Angeles testing machine (Note 1).

Note 1: A procedure for testing coarse aggregate smaller than 37.5 mm (11/2 in.) is covered in Test Method C131/C131M.

1.2 The values stated in SI units are to be regarded as the standard. The inch-pound values given in parentheses are for information only.

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.
