This specification covers mineral-colloid-stabilized, emulsified refined coal tar suitable for use as a weather-protective and petroleum (aliphatic) solvent resistant coating over bituminous concrete pavements.

Formerly under the jurisdiction of Committee D08 on Roofing and Waterproofing, this specification was withdrawn in July 2012 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Реферат

This specification covers mineral-colloid-stabilized, emulsified refined coal tar suitable for use as a weather-protective and petroleum (aliphatic) solvent resistant coating over bituminous concrete pavements. Base refined coal tar emulsion shall be made using binders prepared from a high temperature refined coal tar conforming to the requirements specified for RT11 or higher. The mixtures shall be classified into two types: Type I material is a mixture of refined coal tar emulsion, water, and optional additive and Type II material is a mixture of refined coal tar emulsions, water, aggregate, and optional additive. Aggregate is used in Type II materials to improve traction and wearability. The aggregate shall be either a natural or manufactured aggregate composed of clean, hard, durable particles free of clay and other objectionable material when tested. Different tests shall be performed in order to determine the following physical properties of coal tar: uniformity, wet film continuity, density, residue by evaporation, water content, resistance to volatilization, residue weight loss, solubility of residue in CS2, ash content of residue, aggregate content, drying time, resistance to kerosene, resistance to water, and flexibility.
