Historical Standard: ASTM D3744/D3744M-11 Standard Test Method for Aggregate Durability Index
SUPERSEDED (see Active link, below)
ASTM D3744 / D3744M
1. Scope
1.1 This test method covers the determination of a durability index of an aggregate. The calculated durability index is a value indicating the relative resistance of an aggregate to production of detrimental clay-like fines when subjected to the prescribed mechanical methods of degradation.
1.2 Units The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.2.1 Measurements of volume and mass are only given in SI units because they are the only units typically used in practice when performing this test method.
1.2.2 Measurements in Section 11, Section 15, Equation 3, Equation 4, Table 1, and Figure 2 are only given in inch-pound units because the equipment used in these sections is only manufactured using the inch-pound system.
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.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
