ASTM-D4013 › Standard Practice for Preparation of Test Specimens of Bituminous Mixtures by Means of Gyratory Shear Compactor (Withdrawn 2013)
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
1.1 This practice covers the preparation of 4-in. (101.6 mm) diameter test specimens of bituminous mixtures containing −7/8-in. (–22.4-mm) aggregate.
1.2 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.
1.3 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
The specimens are compacted to simulate the density, aggregate degradation, and structural characteristics possible in the actual road surface when proper construction procedure is used in the placement of the material. The specimens may be used to determine stability, density, strength, water susceptibility, etc., of bituminous mixtures by specified test methods.
