ASTM D5727/D5727M-00(2023)

Die Annotation des Normtextes ASTM D5727/D5727M-00(2023) :

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.
