Abstract: This report describes field and laboratory evaluation of an emulsified asphalt material “Runway Preservation System (RPS),” manufactured by Asphalt Systems, Inc., Salt Lake City, UT. A field application of this material was observed in Portland, OR. An evaluation of the RPS emulsion in regard to ability to seal a pavement surface in relation to other types of sealing indicated that a heavy application could retard the aging of the underlying surface. The durability of the RPS emulsion was compared to an asphalt emulsion by evaluating its ability to hold aggregate under abrasion. The results showed that the RPS emulsion did not appear to have a substantial change in properties with aging, indicating improved durability over the asphalt emulsion.
