AN EVALUATION OF TENSILE STRENGTH TESTING. FINAL REPORT

This report summarizes the findings of Project 3-8-85-432 and describes a series of research activities related to the comparison of the splitting tensile test and the flexure beam test, for quality control and design purposes. This report contains a summary of the activities related to the development, application and use of the splitting tensile test and of the flexure beam test to estimate the tensile strength of portland cement concrete pavement. Information related to the descriptive statistics associated with each test is also summarized. This includes mean strength values, standard deviations and coefficients of variation of concrete batches actually tested. Finally, an empirical equation related to transforming the tensile strength measured by the flexure beam test to a tensile strength value measured by the splitting tensile test is provided.
