Chapter 10: Rigid Pavement Rehabilitation

Anchor: #BCEBACHB

Section 1: Overview

Rigid pavement, if designed and built properly, provides excellent long-term performance with little maintenance required. However, for various reasons, distresses take place 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 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. Not much research has been done on the effectiveness of various repair/rehabilitation strategies. TxDOT recognized this and recently funded several research projects on maintenance-related issues in rigid pavement. As the findings become available, this chapter will be updated.
