(Specification)Standard Specification for Emulsified Refined Coal Tar (Mineral Colloid Type)
Standard Specification for Emulsified Refined Coal Tar (Mineral Colloid Type)
ABSTRACT
This specification covers mineral-colloid-stabilized, concentrated, emulsified, and refined coal tar suitable for use as weather-protective and aliphatic-solvent resistant coatings over bituminous pavements, such as those found at airports, parking areas, and driveways. The emulsion shall be homogeneous and exhibit no separation or coagulation of components that cannot be overcome by moderate stirring. Specimens shall be sampled and shall undergo tests to examine their conformance with physical properties such as uniformity, wet film continuity, resistance to freezing, density, residue by evaporation, water content, resistance to volatilization and residue weight loss, solubility of residue in CS2, ash of residue, drying time, flexibility, and resistance to heat, kerosene, and water.
SCOPE
1.1 This specification covers mineral-colloid-stabilized, concentrated, emulsified, refined coal tar suitable for use as weather-protective and aliphatic-solvent resistant coatings over bituminous pavements, such as those found at airports, parking areas, and driveways. The specification for this material was previously covered by Federal Specification RP355. Note 1Dilute the concentrated emulsion after testing and prior to application to meet the application specification requirements. Application shall be made in accordance with Practice D 3423.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units shown in parentheses are for information only.
The following precautionary caveat pertains only to the test methods portion, Section , of this specification: 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.
