Three mix-design procedures for open-graded asphalt emulsion mixes (Chevron USA, Inc.; U.S. Forest Service Region 6; and Federal Highway Adminsitration Region 10) are summarized. The basic steps used in each method and the major differences among the methods are discussed. Finally, the results of a limited round-robin test program are presented that indicate very little difference in the recommended emulsion and water contents for the three methods. All three procedures are reasonably simple and require little time when compared with those for dense- graded emulsion mixes. However, there is still a need to adopt a standard method of evaluating the strength (or stiffness) of the mix to obtain layer coefficients. Currently, the diametral modulus appears to be the most promising test method available. (Author)
