About This Item
ASTM D4866/D4866M is the ASTM standard that defines a performance specification for coal-tar pitch emulsion pavement sealer mix formulations containing mineral aggregates and optional polymeric admixtures. It is used to support more consistent product evaluation and procurement for pavement sealer materials. By focusing on formulation-related requirements, the standard helps buyers, manufacturers, and specifiers align on expected performance characteristics and material composition in a clear, technical way.
ASTM D4866/D4866M standard overview
This standard addresses mix formulations for coal-tar pitch emulsion pavement sealer products that include mineral aggregates and may also include polymeric admixtures. As a performance specification, ASTM D4866/D4866M is intended to guide how these materials are defined and assessed for use in pavement sealing applications. The document is relevant when a project needs a consistent technical basis for comparing sealer formulations, supporting quality control, and referencing a recognized ASTM standard during specification or purchase.
Where is ASTM D4866/D4866M used?
ASTM D4866/D4866M is commonly used where coal-tar pitch emulsion pavement sealers are specified, produced, or reviewed for technical compliance. It is especially relevant in workflows involving pavement maintenance materials, formulation review, and product submittals that include mineral aggregates and optional polymeric admixtures. The standard may be used by manufacturers, testing organizations, and purchasing teams that need a common reference for evaluating sealer mix formulations before application on paved surfaces.
Practical importance of ASTM D4866/D4866M
In practice, ASTM D4866/D4866M helps reduce ambiguity around what a compliant pavement sealer formulation should represent. That matters for consistency in sourcing, product comparison, and quality control, especially when multiple ingredients or admixture options are involved. Using ASTM D4866/D4866M can support clearer specifications, more reliable evaluation of materials, and better communication between suppliers and users. For organizations that depend on documented standards, it provides a useful technical benchmark for procurement and review.
