ASTM D3320-00

Standard Specification for Emulsified Coal-Tar Pitch (Mineral Colloid Type)

SCOPE
1.1 This specification covers mineral-colloid-stabilized, emulsified coal-tar pitch suitable for use as a weather-protective and aliphatic-solvent resistant coating over bituminous pavements of airports, parking areas, and driveways.  
1.2 The values stated in SI (metric) units are to be regarded as the standard.  
1.3 The following precautionary caveat pertains only to the test method portion, Section 6, of this specification: This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
