The objectives of this research were: (1) To develop recommended test methods for practical laboratory and field measurements of soil resistivity and pH that yield more precise, accurate values than existing methods. Develop practical guidelines for the frequency, location, and interpretation of tests. The recommended test methods may be either modifications of existing tests or new methods developed from different theoretical approaches. (2) To develop correlation factors to compare the results of these recommended methods with the historical record of data obtained through previous methods. (3) To use the recommended test methods, correlate soil resistivity and pH measurements with soil corrosivity, and validate the usefulness of measuring soil resistivity and pH when investigating soil corrosivity. Based on the results of the correlation, develop practical guidelines to assist transportation practitioners with predicting the rate of corrosion in buried structures.
