AASHTO MP 27-16 (2020) PDF Download

AASHTO MP 27-16 (2020) is a standard specification that provides guidelines for the materials used in emulsified asphalt chip seals. A chip seal is a pavement treatment method where emulsified asphalt is applied to the road surface, followed by the application of a single layer of cover aggregate. The standard outlines the quality requirements for both the aggregate and the emulsified asphalt used in chip seals. This ensures that the materials meet certain performance standards and will provide effective and long-lasting chip seal treatments. Additionally, the standard includes an option for a fog seal, which is an additional application of asphalt emulsion to improve the durability and effectiveness of the chip seal treatment.
