Standard Practice for Application of Emulsified Coal-Tar Pitch (Mineral Colloid Type)

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.
