ASTM D4866/D4866M-88 (R2017) PDF Download

ASTM D4866/D4866M-88 (R2017) is a standard performance specification that defines the requirements for mix formulations of coal tar pitch emulsion pavement sealer. These mixtures contain emulsified coal-tar pitch (mineral colloid type), mineral aggregates, and optional polymeric admixtures. The purpose of these mix formulations is to provide a weather-protective coating and resistance against straight aliphatic hydrocarbons for bituminous pavements in various applications such as airports, parking areas, and driveways.

The standard specifies the essential characteristics and properties that these mix formulations must possess to ensure their effectiveness as pavement sealers. It outlines the requirements for the content and composition of the mixtures, as well as the physical and performance properties they should exhibit. This includes factors such as viscosity, specific gravity, particle size distribution, resistance to abrasion, weathering, and resistance to hydrocarbons.

By providing a standard performance specification, ASTM D4866/D4866M-88 (R2017) facilitates consistency and quality control in the production and use of coal tar pitch emulsion pavement sealer mix formulations. This helps ensure that these mixtures meet the necessary criteria for protecting and enhancing the longevity of bituminous pavements in a variety of applications.
