ASTM D5444−15 Standard Test Method for Mechanical Size Analysis of Extracted Aggregate

ASTM D5444−15 Standard Test Method for Mechanical Size Analysis of Extracted Aggregate

Scope
1.1 This test method covers a procedure for determination of the particle size distribution of fine and coarse aggregates extracted from bituminous mixtures using sieves with square openings.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.

Significance and Use
3.1 This test method is used to determine the grading of aggregates extracted from bituminous mixtures.

The results are used to determine compliance of the particle size distribution with applicable specifications requirements, and to provide necessary data for control of the production of various aggregates to be used in bituminous mixtures.
4. Apparatus
4.1 Balances, or scales, readable to 0.1 g and accurate to 0.1 g or 0.1 % of the test load, whichever is greater, at any point within the range of use.
