AASHTO MP 33-17 (2019) PDF Download

AASHTO MP 33-17 (2019) is a standard specification that outlines the quality requirements for emulsified asphalt used in fog seals. A fog seal is a thin layer of emulsified asphalt applied to a pavement surface for various purposes such as providing a surface seal, preventing light raveling, or enhancing visibility through color contrast between traffic lanes and shoulders. Additionally, fog seals can be applied to new chip seals to secure loose chips and improve the visual appearance of the pavement.

This standard ensures that the emulsified asphalt used in fog seals meets specific quality standards. It provides guidelines for the composition, formulation, and testing of the emulsion. These requirements help to ensure that the fog seal achieves its desired objectives such as enhancing pavement durability, reducing maintenance needs, and improving road safety.
