ASTM D244-09 (R2017) PDF Download

Standard Test Methods and Practices for Emulsified Asphalts, also known as ASTM D244-09 (R2017), provides a set of test methods and practices for examining asphalt emulsions. These emulsions are composed of a semisolid or liquid asphaltic base, water, and an emulsifying agent.

The standard covers a range of tests and practices related to the composition, consistency, stability, and examination of residue in emulsified asphalts. Some of the key tests covered in the standard include the measurement of water content, residue and oil distillate by distillation, residue by evaporation, particle charge of cationic emulsified asphalts, viscosity (Saybolt Furol), demulsibility, settlement, cement mixing, sieve test, aggregate coating, miscibility with water, freezing, coating ability and water resistance, storage stability of asphalt emulsion, and examination of residue.

These tests and practices are designed to ensure the quality and performance of emulsified asphalts in various applications.
