Significance and Use
This practice is designed as a guide for architects, engineers, property owners or their representatives, or combination thereof. Its use helps ensure the satisfactory performance of the protective coating system when applied over bituminous concrete pavements.
1.1 This practice covers the application of emulsified refined coal tar slurry meeting the requirements of Specification D6945 Types I and II, by mechanized equipment as a weather protection and petroleum (aliphatic) solvent resistant sealer for use on bituminous concrete pavements. In order to clarify the differences between Types I and II, see 3.3 for standard definition of terms.
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.
