Preservation

Preservation is most often thought of as those preventative maintenance activities undertaken to provide and maintain serviceable roadways and/or planned strategies of cost-effective treatments to an existing roadway and its appurtenances that preserve the system, retard future deterioration, and maintain the functional condition of the system. In addition, the process used to extend the functional condition by adding longer life to the roadway surface without increasing the structural capacity of the roadway can be defined as preservation.

For purposes of accounting and reporting under BARS, the costs of preservation are defined as performing those specialized maintenance activities that serve to extend the originally estimated life of each type of roadway, roadway structure, and facility but do not increase its traffic flow capacity or efficiency. This account should not include maintenance or construction.

CRAB assists counties in their roadway preservation efforts in two different ways. The County Arterial Preservation Program is a resource dedicated to the preservation of paved county arterials throughout Washington State. In order to retain their eligibility for CAPP funds each year, counties are required to use a pavement management system (PMS) to assist their project selection and decision process.
