Abstract:

Formed concrete cylinders, cylinders cored from concrete slabs, and formed concrete beams were cured and tested to investigate the usefulness of the splitting tensile test in determining the flexural strength of portland cement concrete pavements. Three length-to-diameter ratios of cylinders, three types of bearing pads, and cylinders with and without reinforcing wire were investigated in this study. Test data analysis established that the length-to-diameter ratio which should be used is two 2 and defined an equation for converting splitting tensile strength to flexural strength. Data showed that test results from either formed or cored specimens could be used to indicate flexural strength, that the presence of wire reinforcement had little effect on results, and that the type of bearing pad was of little consequence.
