Earthfill construction involves three phases: transportation of concrete from mixer to site, spreading of the concrete in lifts at the site, and compaction of the concrete. The concrete arrives at the site by dump truck, instead of by bucket or ready-mix truck, and the concrete is compacted with vibrating steel-wheel rollers, instead of immersion vibrators. These methods allow a very rapid construction time. The concrete used is considered "no slump" concrete. This means that if a small cup is filled with concrete before it sets, and then turned over and the cup taken away, it will not lose any height. A lower slump means there is less water present, and with less water present, the concrete will obtain higher final strength.. The concrete does not need to be workable because it is placed and vibrated in mass. Placement rates of 5,800 to 12,400 cubic yards per day (4440 and 9480 cubic meters per day) have been achieved and one to two years have been saved in the construction time of large dam projects. This rapid construction time allows costs to be decreased by one-half and up to one-third of traditional concrete dam cost. Soil-cement embankment dams utilize this same method of construction, however they do not produce the same strength as an RCC dam.

Roller-compacted concrete differs from conventional concrete in its placement methods. RCC dams gain the strength of conventional concrete dams while also gaining the dramatically lower price associated with earthfill methods of construction. The earthfill methods of placement allows much lower workability and allows increased placement rates that dramatically lower the cost of the project.
