ASTM D3202-94(2000)

Standard Practice for Preparation of Bituminous Mixture Beam Specimens by Means of the California Kneading Compactor

SCOPE
1.1 This practice covers the preparation of beams of bituminous paving mixtures by means of a mechanical compactor that imparts a kneading action compacting the beam by a series of individual impressions made with a ram.  
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
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.
