Scope and objective This report presents a discussion of the equipment and special construction procedures associated with the compaction of RCC. It includes characteristics of the mixture relevant to compaction and the effects of compaction on desired properties of RCC. These properties include various strength parameters@ watertightness@ and durability. Differentiation is made between RCC used in massive concrete work and that used in pavements. The discussion also includes provisions for measurement of compaction. This report does not cover soil-cement or cement-treated base. The objective of this report is to summarize experience in compaction of RCC in various applications@ to offer guidance in the selection of equipment and procedures for compaction@ and in quality control of the work.
