ASTM D977-19a

Standard Specification for Emulsified Asphalt

ABSTRACT
This specification covers the requirements for thirteen grades of emulsified asphalt for use in pavement construction in the manner designated. The emulsified asphalts shall be homogeneous after thorough mixing and shall be tested within 14 days of delivery. Asphalts separated by freezing shall no longer be tested. Materials shall be appropriately sampled and tested, and shall conform accordingly to the following physical requirements: viscosity; storage stability; demulsibility; coating ability and water resistance; cement mixing; residue by distillation; oil distillate; ductility; solubility in trichloroethylene; and behavior during sieve, penetration, and float tests.
SCOPE
1.1 This specification covers 13 grades of emulsified asphalt for use in pavement construction in the manner designated.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
