Road roller - Wikipedia
A road roller (sometimes called a roller-compactor, or just roller) is a compactor-type engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations.Similar rollers are used also at landfills or in agriculture. Road rollers are frequently referred to as steamrollers, regardless of their method of propulsion.
COMPACTION OF CONCRETE – PURPOSE, PROCESS & EFFECT ...
Compaction is the process that expels entrapped air from freshly placed concrete and packs the aggregate particles together so as to increase the density of the concrete. The compacting and finishing of concrete are generally two separate operations but sometimes, particularly with flat horizontal surfaces, they become parts of the one operation.
