An overview of various assessment techniques is discussed, including visual assessment as well as more detailed destructive and non-destructive assessment techniques, such as mechanical sounding, half-cell potential surveys, corrosion rate testing, material sampling, and laboratory analyses. Digital data collection techniques and the use of assessment data to develop service life and durability predictions based on the properties gathered by an in-situ assessment are also presented. Based upon the assessment results, the appropriate mitigation strategies can be selected. Several repair and mitigation strategies for reinforced concrete structures are discussed, along with the considerations involved with selecting each system with respect to cost, maintenance, and potential service life implications. Representative case studies will illustrate how these tools have been used for water and wastewater infrastructure.
