ASTM D6929-04

Standard Practice for Freezing of Emulsified Asphalts

SIGNIFICANCE AND USE
Certain agencies, who desire to use, store, or transport emulsified asphalt under less than ideal weather conditions, may require that the product remain homogeneous (unbroken) after being subjected to temperatures of −18°C.
SCOPE
1.1 Emulsified asphalt is normally damaged by freezing temperatures, but specially formulated materials are expected to pass this practice.
1.2 This practice 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.
