Road roller, also known as 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. The first road rollers were steam-powered and used a large drum to compact the material. Internal-combustion-powered rollers were introduced in the early 20th century and quickly replaced steam rollers. Road rollers come in a variety of sizes and types, depending on the application. Small rollers, typically weighing less than 10,000 pounds, are used for compacting small areas, such as sidewalks or driveways. Larger rollers, weighing up to 100,000 pounds, are used for compacting large areas, such as highways or airfields. Road rollers are typically powered by a diesel engine, which drives a hydraulic system that turns the drum. The drum is typically made of steel and is covered with a layer of rubber to prevent it from damaging the surface being compacted.
Road rollers are used in a variety of ways. They are used to compact the base course of a road, which is the layer of aggregate or granular material placed underneath the asphalt or concrete pavement. Proper compaction of the base course provides a stable foundation for the road and helps distribute loads evenly. Road rollers are also used to compact the asphalt or concrete pavement itself. This helps to create a smooth, even surface that is resistant to cracking and wear. Road rollers are a versatile and essential piece of construction equipment. They are used in a variety of applications to create safe, durable roads and foundations.
