Abstract:
The project was designed to determine if emulsified asphalts would perform as well as cut-back asphalts in similar applications. The benefits of emulsified asphalts are primarily derived from the lower temperature requirements and occasionally a lesser amount of actual asphalt content. The project was undertaken in two phases; Phase I--Tack Coats and Phase II--Seal Coats for Surface Treatments. The application of the tack coats in Phase I and the surface treatments in Phase II followed generally the rates that are commonly used in the maintenance operations. Three different types of surface treatments were used; seal coat with sand using anionic emulsion, a chip seal with a sand cover using cationic emulsion and a hot maintenance mix. All of these treatments were placed over areas previously treated with hot maintenance mix in 1974.
