AASHTO PP 88-17 (2021) PDF Download

AASHTO PP 88-17 (2021) is a standard practice that provides guidelines for the design of emulsified asphalt fog seal mixtures. The purpose of this standard is to determine the proportions of various components, such as emulsified asphalt, mineral aggregate, water, mineral filler, and additives, in order to produce a slurry seal job-mix formula. The mixture properties are used as criteria for evaluating and designing the fog seal mix.

By following this standard practice, engineers and practitioners can ensure that the fog seal mixture meets the desired performance and durability requirements. The mixture design process involves evaluating various factors, such as aggregate gradation, asphalt emulsion properties, additives, and curing conditions. These factors are carefully considered to optimize the fog seal mix design and ensure its effectiveness in enhancing the pavement surface.
