Chapter 10: Rigid Pavement Rehabilitation

Anchor: #i1004665

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.
