Abstract: The design and construction of a 300-ft high sloping-core rockfill dam is described. The bulk of the rock in the dam was placed in 18-in. lifts, sluiced lightly and compacted with four coverages of a 50-ton rubber-tired roller. The high density obtained by this method of construction has resulted in extremely low settlements. To date (1965) the settlement has only totaled 0.4 ft under the 300-ft maximum section. This is 0.14% of the height. Methods of producing and handling finer sized quarry rock suitable for roller compaction are examined. By efficient quarrying methods, the contractor was able to place the rolled rock in the embankment for $0.62 per cu yd. This compares with $0.65 per cu yd cost for the conventionally dumped and sluiced big rock in the outer shell of the embankment.
