Abstract

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.

This abstract is a brief summary of the referenced standard.

ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This practice covers the application of mineral-colloid-stabilized, emulsified coal-tar pitch meeting the requirements of Specification D3320 , 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 non-conformance 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 and health practices and determine the applicability of regulatory limitations prior to use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
