Standard Specification for Emulsified Refined Coal-Tar (Driveway Sealer, Ready to Use, Primarily Residential Grade) (Withdrawn 2012)
The following bibliographic material is provided to assist you with your purchasing decision:
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.
Scope
1.1 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.
1.2 Both products specified are prepackaged ready to use driveway sealers primarily for retail homeowner use.
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 requirements prior to use.
