Chronic Rehabilitation

Definition - What does Chronic Rehabilitation mean?

Chronic rehabilitation is a term used to refer to the regular maintenance of a component that is required over its serviceable life.

Chronic rehabilitation can be costly and resource intensive in the long run, as regular inspection, assessment and repair are required periodically to ensure that the component in question operates as intended.

Trenchlesspedia explains Chronic Rehabilitation

Chronic rehabilitation is required on manhole sections, particularly at the manhole chimney. The chimney is comprised of an assembly of concrete adjustment rings which have a tendency to split, crack and crumble at the joints resulting in unwanted water infiltration.

A solution to this problem involves using a single precast unit for the chimney to replace the assembly of adjustment rings. This eliminates the need for chronic rehabilitation required due to increased traffic loading, freezing and thawing cycles and pavement impact.
