Chapter 10: Rigid Pavement Rehabilitation
Section 1: Overview
Rigid pavement, if designed and built properly,
provides excellent long-term performance with little maintenance
required. However, for various reasons, distresses occur and repair/rehabilitation becomes
necessary. Compared with repair/rehabilitation of flexible pavement,
rigid pavement repair/rehabilitation costs more and, if not done
properly, similar distresses will develop in close proximity, and
additional repair/rehabilitation will be required. Developing optimum
repair/rehabilitation strategies requires the understanding of the
causes and mechanisms of the distress. The number of distress types
in rigid pavement is limited and the causes are fairly well understood.
In this chapter, pavement distress types that require specific repair/rehabilitation
strategies are described along with repair procedures.
