Abstract:

The initial phase of a multiphase investigation program was completed by USBR (U. S. Department of the Interior, Bureau of Reclamation) personnel to develop geotechnical laboratory testing techniques for RCC (roller-compacted concrete). This phase was designed to investigate use of soil compaction techniques with RCC and to make comparisons between soil and concrete methods for determining unit weight. The testing program was formulated to evaluate effects of compactive effort and low plasticity fines content on an RCC mix currently used in USBR research. Compressive strength and durability tests were performed on compacted test specimens. USBR soil and soil-cement laboratory test procedures were modified for use in the testing program. Index unit weight and concrete consistency tests were performed for comparison purposes. Laboratory test data were evaluated using traditional soil and concrete theory.
