ASTM D6926-20 使用马歇尔设备制备沥青混合物样品的标准实践

1.1 This practice covers preparation and compaction of 4 in. (101.6 mm) diameter by nominal 2.5 in. (63.5 mm) high cylindrical asphalt paving mixture specimens. This practice is intended for use with laboratory and plant-produced asphalt mixtures with aggregate up to 1 in. (25.4 mm) maximum size and for recompaction of asphalt paving mixture samples. NOTE 1—Historically, 35, 50, and 75 blows per face has been practiced for this test. NOTE 2—Manufacturers do not recommend applying an excessive number of blows per face of a sample. This practice has been known to cause fatigue and damage to machine components. 1.2 There are three types of Marshall compaction apparatus in use. The following types of hammer arrangements are included in this practice: 1.2.1 Manually held hammer handle (Type 1) is attached to a flat compaction foot through a spring-loaded swivel and is hand operated (see 5.3.1) (original standard developed by the United States Army Corps of Engineers). 1.2.2 Hammer handle restrained laterally (fixed) but not vertically (Type 2), attached to a flat compaction foot through a spring-loaded swivel and is either mechanically or hand operated (see 5.3.2). There may or may not be a constant surcharge on top of the hammer handle. Mechanical hammers (Type 2) are available that operate at a range of 55 to 68 blows per minute. 1.2.3 Hammer handle restrained laterally (fixed) with or without constant surcharge on top of hammer, is attached to a slanted compaction foot on a rotating mold base (Type 3), and is mechanically operated (see 5.3.3). This method must be used as a referee method. 1.3 Although the mass and height of mass drop for each apparatus are the same, density achieved in compacted specimens with the same number of blows will be different. It is up to the owner or specifier to establish the specific required number of blows to be used for compaction of the specimen in relation to the field. 1.4 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

No other units are included in this standard. 1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
