Evaluation of Concrete Characteristics for Rigid Pavements

Year: 1998
VTRC No.: 98-R24
Abstract: The researcher developed correlations among flexural, split tensile, and compressive strengths and ultrasonic pulse velocity from laboratory testing using materials and mix designs proposed for use in a paving project. These relationships were used to review the current Virginia Department of Transportation specifications and quality control procedures for concrete used in the construction of rigid pavements. Correlations between compressive and flexural strength for project-specific materials and mix designs permit the use of compressive strength cylinders rather than beams for compliance testing. The relationships also provide a means for evaluating the quality of the concrete as placed in the pavement.
