Significance and Use

The CKE furnishes an index, designated as the K factor, that indicates the aggregate particle roughness and surface capacity based on porosity.

The CKE is used as part of the Hveem mix design procedure to determine the approximate bitumen ratio (ABR), as shown in Appendix X1. However, there are other applications such as determining the coarse aggregate fraction constant (Kc) for use as an aid in selecting a bitumen content for open-graded friction courses.

Scope

1.1 This test method determines the centrifuge kerosine equivalent (CKE) of aggregate used in bituminous mixtures.

1.2 Units of Measure:

1.2.1 With regard to sieve sizes and size of aggregate as determined by the use of testing sieves, the values in inch-pound units are shown for the convenience of the user, but the standard sieve designation shown in parentheses is the standard value as stated in Specification E 11.

1.2.2 With regard to other units of measure, the values shown in parentheses are for information purposes.

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. For specific hazard statements, see 7.1.
