AASHTO PP 88-17 (2019) Standard Practice for Emulsified Asphalt Fog Seal Design is a guideline for determining the proportions of different materials to create a slurry seal job-mix formula. The standard utilizes mixture properties to evaluate and determine the quantities of emulsified asphalt, mineral aggregate, water, mineral filler, and additives required to produce the desired fog seal.

Emulsified asphalt fog seals are commonly used to extend the life of asphalt pavements by providing a protective coating and reducing oxidation and moisture infiltration. This standard provides a systematic approach for designing fog seals, ensuring that the right proportions of materials are used to achieve the desired performance and durability.

By using mixture properties, this standard enables engineers and practitioners to effectively evaluate and determine the appropriate combination of materials for fog seal design. This helps ensure that fog seals are properly formulated and applied, leading to enhanced pavement performance and longevity.
