1.1 This practice covers the application of mineral-colloid-stabilized, emulsified coal-tar pitch meeting the requirements of Specification D5727/D5727M, as a weather protection and aliphatic-solvent-resistant sealer for use on bituminous pavements of airports, parking lots, and driveways.

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 nonconformance with the standard.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.


This practice covers the application of mineral-colloid-stabilized, emulsified coal-tar pitch, as a weather protection and aliphatic-solvent-resistant sealer for use on bituminous pavements of airports, parking lots, and driveways. The procedure for preparation of (1) old asphalt surfaces, (2) new asphalt surfaces, and (3) emulsion, and the procedure for application of emulsion for the first coat and second coat are detailed. When sand addition to the top coat of the emulsion is necessary, the sand shall meet the prescribed sieve size requirements. Application precautions including weather conditions, pavement and air temperatures, drying time, and emulsion freezing are also provided.
