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

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 costeffectiveness, and reducing user delays. - Consensus definition from AASHTO, Industry Representatives, and FHWA

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

Types of Maintenance Activities 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

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

Preventive Maintenance n n Planned Performed on good pavements Contributes to longterm performance Examples: Fog Seal, Chip Seal, Cape Seal, Thin HMA Overlay, Crack Seal

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

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

Public Perceptions n n 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

Summary n n n 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.
