Rejuvenating seal is part of Santa Barbara County’s preservation program Integrating Pavement Preservation Practices By Kevin Donnelly T he county of Santa Barbara has developed and maintained an award-winning nationally recognized pavement preservation program that is extending the life of its pavement network through the use of pavement preservation practices, including fi scal tracking and condition surveys using asset management software. These practices have been integrated into the county public works planning to provide powerful tools for budgeting in the face of increasingly limited funding. PROBLEM OR CHALLENGE? In 1995, the county of Santa Barbara Public Works Department maintained its pavement network by allocating funding on roadways that were in the worst condition, while neglecting those roadways that had been recently paved. The life expectancy of a newly paved roadway was about 15 to 20 years and there was little funding left to extend the pavement life beyond that time period. This worst first strategy seemed to be dictated by the “squeaky wheel,” or how many calls came into the county related to a specific road. No real plan or vision existed for treating this system of over 1,600 lane miles. During this time, roadways to be treated were selected by three regional road yard superintendents — and the “squeaky wheel” — while no consideration was given to gaining economies of scale by geographically grouping these projects. The county’s pavement management system (PMS) was minimal and depended on limited windshield assessments of pavement condition, without collecting data on specific distresses or work history, to track pavement performance. There was a lack of communication about budget and cost effectiveness; funding was very limited and high dollar projects treated only a minimal amount of lane miles. The county’s system continued to deteriorate. In 1999, the county made the shift to a formal pavement preservation program. Components of the county’s pavement management program include the road maintenance annual plan, and software to leverage GIS technology, field assessments and ongoing performance measures. The county’s corrective maintenance forces were strategically deployed to complement the preventive maintenance program. Low-cost treatments were applied by the county to extend the life of the existing “good” pavements, while using the newly realized cost savings to bring “bad” pavements into the preventive maintenance cycle. Consistent processes and communication between the three road maintenance yards was greatly improved and projects were geographically grouped to gain economies of scale. The county also simultaneously upgraded its pavement management system (PMS) to MicroPAVER (www.cecer. army.mil/paver/Index.htm), which allowed for more detailed inventory, pavement inspection data, condition ratings and work history. Staff was able to create deterioration models, perform condition analysis and gained powerful budget, work planning and needs assessment tools. This new technology allowed the county to focus on the cost benefit and service life of all the pavement treatments available.
