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 thirteen 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.
