Workers apply an application of scrub seal, a polymer specifically formulated for pavement preservation that features unique chip retention emulsion with a rejuvenating agent, to an Alaska roadway. The work is part of research expected to improve road preservation and reduce road maintenance expenses.

Abstract

This project will assist the ADOT&PF and local Alaska agencies in identifying pavement preservation treatments suitable for specific environmental regions within the state. Expected benefits of this study include cost savings (studies have shown an active pavement preservation program can offer more than 50% cost savings over a life cycle of 20 years); energy and emissions savings (pavement preservation treatments are green treatments); and satisfied users (less skid and noise). Research results will provide the State with information on the types of preservations most suitable for Alaska; information on performance of pavement preservation treatments used in Alaska; a strategy selection guide for treatments; recommendations on building a program; and recommendations for implementing a comprehensive Asset Management program. This project is a joint venture between Caltrans, AUTC, and ADOT&PF. The majority of the work will be performed at the California Pavement Preservation Center. UAA and UAF researchers will contribute to data analysis and to preparation of guidance materials for ADOT&PF.
