ABSTRACT
ABSTRACT: Pavement preservation has been an important topic for flexible pavements for many years. It was not until the Foundation for Pavement Preservation (FP2) was established in 1992 that it became an important aspect in the area of system maintenance and preservation. There are several types of treatments included in the pavement preservation tool box including thin HMA overlay, chip seals, slurry surfacings, and cape seals. This paper addresses the definitions, types of treatments currently included in the tool box, the reported benefits of the treatments (including, cost, energy and environmental), and the challenges still facing agencies in documenting the benefits and increasing the use of these types of treatments. Recent developments with funding pavement preservation and rehabilitation and the implications of the new Technical Advisory for the ADA act are also discussed.
