ASTM D2397/D2397M-20 PDF Download

The ASTM D2397/D2397M-20 standard, also known as the Standard Specification for Cationic Emulsified Asphalt, outlines the requirements for the seven grades of cationic emulsified asphalt that are used in pavement construction. The standard ensures that the asphalt is homogeneous after thorough mixing and has not separated due to freezing.

The specification covers various characteristics of the asphalt, including viscosity, storage stability, demulsibility, coating ability, water resistance, particle charge, and distillation. These characteristics are important for ensuring the quality and performance of the cationic emulsified asphalt in pavement construction.

By conforming to the requirements set in this standard, manufacturers and suppliers of cationic emulsified asphalt can ensure the consistency and reliability of their products in terms of performance and durability. Compliance with this standard also helps ensure that the asphalt will meet the specified requirements for use in pavement construction projects.
