Abstract:
This article discusses two test methods that have a potential to help the concrete paving industry place better quality pavements at lower cost—the vibration Kelly ball (VKelly) test and the ultrasonic pulse velocity (UPV) test. The VKelly test appears to provide useful information regarding the response of a mixture to vibration. The proposed UPV approach looks promising for predicting sawcutting times in the field.
