ASTM D6114/D6114M−09 Standard Specification for Asphalt-Rubber Binder

ASTM D6114/D6114M−09 Standard Specification for Asphalt-Rubber Binder

Scope
1.1 This specification covers asphalt-rubber binder, consisting of a blend of paving grade asphalt cements, ground recycled tire (that is, vulcanized) rubber and other additives, as needed, for use as binder in pavement construction.

The rubber shall be blended and interacted in the hot asphalt cement sufficiently to cause swelling of the rubber particles prior to use.

NOTE 1—It has been found that at least 15 % rubber by weight of the total blend is usually necessary to provide acceptable properties of asphalt-rubber.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Combining values from the two systems may result in non-conformance with the standard.

1.3 The following precautionary caveat pertains to the test method portions only, Sections 4 and 5 of this

Specification:

This standard does not purport to address all of the safety concerns, if any, associated with its use.
