The Dalles Pavement Preservation Program

1. The DallesPavement Preservation Program Presented by Bill Barrier Transportation Manager City of The Dalles Public Works Department

2. Issues • What is pavement preservation? • What is preventive maintenance? • What is corrective maintenance? • When should these actions be taken? • Are these activities effective? • If so, then why doesn’t everyone have a pavement preservation program?

3. What is Pavement Preservation? Pavement preservation is the sum of all activities undertaken to provide and maintain serviceable roadways, including preserving the investment in the national highway system, extending pavement life, enhancing pavement performance, ensuring cost-effectiveness, and reducing user delays. - Consensus definition from AASHTO, Industry Representatives, and FHWA

4. Components of Pavement Preservation • Includes all types of maintenance activities (i.e., routine, reactive, corrective, and preventive) • Includes minor rehabilitation activities • Does not include major rehabilitation or reconstruction

5. Type Planned? Before Deterioration? Extends Facility Life? Routine Yes Not Necessarily Sometimes Reactive (Demand) No No Probably Not Corrective Generally No Sometimes Preventive Yes Yes Yes Types of Maintenance Activities

6. Preventive Maintenance The planned strategy of cost effective treatments to an existing roadway system and its appurtenances that preserves the system, retards future deterioration, and maintains or improves the functional condition of the system (without increasing structural capacity). - AASHTO’s Standing Committee on Highways

7. Preventive Maintenance • Planned • Performed on good pavements • Contributes to long-term performance • Examples: Fog Seal, Chip Seal, Cape Seal, Thin HMA Overlay, Crack Seal

8. East 10th and Dry Hollow

9. Corrective Maintenance • Reactive • Performed on failing pavements • Does not contribute to long-term performance • Examples: Patching, Pothole Repair

30. West 11th – Trevitt to Union

31. Cost Comparison of Options • Preventive maintenance: $ 10,270 • Rehabilitation: $ 45,570 • Reconstruction: $ 574,000 Costs obtained from City of Bedford (Texas) on a per-lane mile basis

32. Public Perceptions • Public averse to steering maintenance dollars toward pavements in good condition • Agencies more likely to receive complaints about specific defects than overall network • Challenge of balancing limited maintenance resources between preventive maintenance and rehab/recon • Need to educate the public about new philosophy

33. Summary • Backlog of deferred maintenance has resulted in more streets needing rehab/recon. • Preventive Maintenance is more cost effective in the long run than relying on rehab/recon. • There is a need to fund both Preventive Maintenance to maximize street life and to rehabilitate failed streets.
