Investigation of Optimized Graded Concrete for Oklahoma

This report presents the results of several novel test methods to investigate concrete for slip formed paving. These tests include the Box Test, a novel test to evaluate the response of concrete to vibration, the Aggregate Imaging Measurement System 2 (AIMS2), an automated test for aggregate shape and texture, and the use of a pan mixer to serve as a concrete rheometer. The results show that both the Box Test and AIMS2 tests seem to be useful and provide reliable data. The pan mixer results do not appear to be reliable. The establishment of these test procedures provides a basis for future investigations of materials and mixtures from the state of Oklahoma.
