Smooth wheel rollers are one of the most common types of compaction equipment used. We've all seen them in action on a highway during the summer. They are a standalone piece of equipment that have an engine, move very slowly and their weight is used to provide compaction. They are typically used for base layers of soil or for asphalt pavement.
