ASTM D7229-08(2013)e1

Standard Test Method for Preparation and Determination of the Bulk Specific Gravity of Dense-Graded Cold Mix Asphalt (CMA) Specimens by Means of the Superpave Gyratory Compactor (Withdrawn 2021)

SIGNIFICANCE AND USE
4.1 This test method is used to prepare specimens for determination of the bulk specific gravity of a cured compacted specimen. It covers modifications to Test Method D6925 for preparation of CMA by means of the SGC.  
4.2 This test method is useful for monitoring the density of the specimen during the compaction process. It is suitable for laboratory design and field control of CMA.  
4.3 Local end-use specifications should be developed to establish conformance to the job and user requirements.
SCOPE
1.1 This test method concerns the preparation and compaction of cylindrical specimens of dense-graded cold mix asphalt (CMA) using the Superpave gyratory compactor (SGC).  
1.2 This test method is applicable for road mixes or plant mixes prepared at ambient temperatures.  
1.3 This test method also refers to the determination of the bulk specific gravity of the compacted CMA.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 A precision and bias statement for this test method has not been developed at this time. Therefore, this test method should not be used for acceptance or rejection of a material for purchasing purposes.  
1.6 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.
WITHDRAWN RATIONALE
This test method concerned the preparation and compaction of cylindrical specimens of dense-graded cold mix asphalt (CMA) using the Superpave gyratory compactor (SGC).
Formerly under the jurisdiction of Committee D04 on Road and Paving Materials, this test method was withdrawn in May 2021. This standard is being withdrawn without replacement due to its limited use by industry.
