Section 1: Overview

This manual includes step-by-step repair procedures for use on new and existing concrete members cast for the Texas Department of Transportation (TxDOT). It includes a comprehensive list of common concrete distress and repair methods. The methods adhere to industry standards and the provisions from applicable documents by the American Concrete Institute and American Society for Testing and Materials. This manual was developed in collaboration with various repair material manufacturers to ensure that the procedures meet common proprietary requirements.

In general, repairs to TxDOT concrete structures should be implemented in accordance with the methods outlined in this manual. However, unusual circumstances occasionally arise. Engineers may determine that methods differing from those outlined here are more appropriate in some circumstances.

Updates to the manual are summarized in the following table.
