Pavement Preservation

Pavement Preservation is "a program employing a network level, long-term strategy that enhances pavement performance by using an integrated, cost-effective set of practices that extend pavement life, improve safety and meet motorist expectations."

• An effective pavement preservation program will address pavements while they are still in good condition and before the onset of serious damage.

• Applying a cost-effective treatment at the right time, the pavement is restored almost to its original condition.

• The cumulative effect of systematic, successive preservation treatments is to postpone costly rehabilitation and reconstruction.

Pavement Preservation

• During the life of a pavement, the cumulative discount value of the series of pavement preservation treatments is substantially less than the discounted value of the more extensive, higher cost of reconstruction and generally more economical than the cost of major rehabilitation.

• Additionally, performing a series of successive pavement preservation treatments during the life of a pavement is less disruptive to uniform traffic flow than the long closures normally associated with reconstruction projects.

Pavement PreservationRoutine Maintenance

Routine Maintenance "consists of work that is planned and performed on a routine basis to maintain and preserve the condition of the highway system or to respond to specific conditions and events that restore the highway system to an adequate level of service."

Source: AASHTO Highway Subcommittee on Maintenance

Routine Maintenance activities are often "in-house" or agency-performed and are not normally eligible for Federal-aid funding.

Pavement PreservationPreventative Maintenance

Preventive Maintenance is "a 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 significantly increasing the structural capacity)."

Source: AASHTO Standing Committee on Highways, 1997

As a major component of pavement preservation, preventive maintenance is a strategy of extending the service life by applying cost-effective treatments to the surface or near-surface of structurally sound pavements.

Pavement PreservationPavement Rehabilitation

Minor Rehabilitation consists of non-structural enhancements made to the existing pavement sections to eliminate age-related, top-down surface cracking that develop in flexible pavements due to environmental exposure. Because of the non-structural nature of minor rehabilitation techniques, these types of rehabilitation techniques are placed in the category of pavement preservation.Source: AASHTO Standing Committee on Maintenance Definition

Minor Rehabilitation

EXAMPLE PCI = 55 to 25 Poor• 1.25” – 2.0” Overlay Only ($5.25 to $9.00/SY)

Increase pavement thickness to strengthen existing pavement sections to accommodate existing or projected traffic loading conditions
