A road roller is a compactor type engineering vehicle, which is used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations. Also, road rollers are used in landfills and agriculture. The rolling process ensures that foundations are compacted thoroughly so the materials are compact, and do not come loose. Rollers are equipped with basic features such as diesel engine, canopy to protect the driver, drum(s), which can be a vibratory smooth drum or a static smooth drum, tires, a compaction meter to measure the level of compaction and a water system.

An analysis of the Use of road rollers

Road rollers are iconic in the construction industry. In history, they started as simple stone cylinders being pulled by people to flatten the earth a bit, soon they made animals pull large stone cylinders or wooden planks as a means to flatten the earth. And then when the age of metal came, the rollers finally came into play. This piece of heavy equipment is one of the most common machines to find in construction sites, mainly because they are mostly used at the beginning stages when the foundation of the building is being built.

A road roller is a compaction vehicle used to compact soil, gravel, asphalt, crushed stone sub-base layer or some other site surface material. Rollers are most often used for road construction or for creating compact foundations for large areas although they can also be used in areas as diverse as on landfill sites or agricultural projects.The primary use for rollers is to crushing equipment, knead or vibrate loose materials by applying direct pressure. The rolling process is used to compact loosely bound foundation materials, so they remain compacted and do not come loose.

Road rollers use the weight of the vehicle to compress the surface being rolled or use mechanical advantage (vibrating). Initial compaction of the substrate on a road project is done using a padfoot drum roller, which achieves higher compaction density due to the pads having less surface area. Rollers are also used in landfill compaction. Such compactors typically have padfoot or “sheep’s foot” drums, and do not achieve a smooth surface. The pads aid in compression, due to the smaller area contacting the ground.
