Abstract:

Roller-compacted concrete (RCC) pavements are durable and can be built rapidly and economically. In previous research, the gyratory compactor has proved to be a reliable instrument and overcome the drawbacks of other methods used to mold laboratory and field samples. Work is under way by different organizations in Canada, Japan, and the United States to improve mix design procedures for RCC. One procedure widely used for RCC pavements was developed by the U.S. Army Corps of Engineers. This research investigated improving mixture proportioning of RCC by using a gyratory compactor. Previous research suggested that the gyratory compactor could be used effectively to produce RCC test samples for both compressive and splitting tensile strength. An RCC mix design procedure using the gyratory compactor can benefit many transportation agencies because it provides a reliable way to evaluate the strength and density of RCC mix designs. Results for several RCC mixtures compacted to different densities are presented, along with comparisons with modified Proctor test results. Using the gyratory compactor to design better RCC mixtures might lower the costs and improve the reliability of RCC pavements.
