This specification covers the seven grades of cationic emulsified asphalt for use in pavement construction. The asphalt shall be homogeneous after thorough mixing provided separation has not been caused by freezing and shall conform to the requirements set for viscosity, storage stability, demulsibility, coating ability and water resistance, particle charge, and distillation.

1.1 This specification covers seven grades of cationic emulsified asphalt for use in pavement construction in the manner designated.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
