碾压混凝土正首次用于一座混凝土拱坝的维修。这座拱坝位于加利福尼亚州圣巴巴拉以北大约16.7km处,称为直布罗陀拱坝,维修工作将于1989年初完成。1979年,这座拱坝已被认为不能承受地震或可能最大洪水的非常荷载条件。碾压混凝土方法是经过对3个比较方案的设计、环境、施工和造价的评估后才选定的。另外几种被考虑的方法是对坝体上、下游面铺筑钢筋混凝土或喷浆混凝土复盖 RCC is being used for the first time for the repair of a concrete arch dam. This arch dam, located about 16.7km north of Santa Barbara, California, is called the Gibraltar Arch Dam and maintenance work will be completed by early 1989. In 1979, the arch dam was considered to be unable to withstand the extraordinary load conditions of an earthquake or possibly the largest flood. The RCC method was selected after evaluation of the design, environment, construction and cost of the three comparative schemes. Several other methods are considered for the dam body, the downstream face of the laying of reinforced concrete or shotcrete cover
