ASTM D3423/D3423M-84(2011)e1

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.
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.

3. Preparation of Surface
3.1 Old Asphalt Surfaces (those which have weathered over a change of seasons):
3.1.1 Repair and patch all pavement defects. If a solvent containing cold-applied material is used, this should be done a
minimum of 90 days prior to the planned application of the sealer to permit solvent escape before sealing.
3.1.2 Thoroughly inspect the pavement surface for minor cracks or other imperfections. Ignore hairline cracks. Open minor
cracks (less than 12.7 mm ([ ⁄2 in.))in.]) to a minimum depth and width of 12.7 mm and fill with a crack filler approved by the
manufacturer of the sealer. Wider cracks, along with soft or sunken spots, indicate that the pavement or the pavement base should
be repaired or replaced.
3.1.3 Treat old, badly oxidized asphalt pavement or asphalt pavement that has lost binder by erosion leaving exposed aggregate
with a prime coat recommended by the sealer manufacturer after all loose aggregate is removed. This prime coat is to dry
thoroughly before proceeding.
3.1.4 Immediately prior to application of the sealer, clean the surface of all loose dust, dirt, leaves, and other foreign materials
by sweeping, by flushing well with water, or a combination of both.
3.1.5 Remove oil or grease that has not penetrated the asphalt pavement by scrubbing with a detergent until a water-break-free
surface is obtained after thorough flushing with clear water. If cleaning is unable to produce a true “water-break-free” surface, and
the size of the unsatisfactory area is too small to warrant replacement as described in 3.1.1, the questionable area should be treated
with a spot sealer as per the pavement sealer manufacturer’s recommendation. Do not use only solvents to remove oil or grease
as the solvents may affect adhesion of the sealer.
This practice is under the jurisdiction of ASTM Committee D08 on Roofing and Waterproofing and is the direct responsibility of Subcommittee D08.09 on Bituminous
Emulsions.
