This circular addresses the current state of practice within the emulsified asphalt industry and examines new test methods that eventually could redefine how the industry determines specifications and performance of emulsified asphalts. It is the outcome of a workshop, Progress Towards Performance-Graded Emulsified Asphalt Specifications, sponsored by the Characteristics of Asphalt Materials Committee at the 92nd Annual Meeting of the Transportation Research Board. The circular is a progress report that builds on two e-circulars published in 2006 and 2007, Transportation Research Circular E-C102: Asphalt Emulsion Technology and Transportation Research Circular E-C122: Asphalt Emulsion Technology: Review of Asphalt Emulsion Residue Procedures, which covered various specific topics on emulsified asphalt technology. A workshop overview and six papers are included in the circular.
