A road roller is a heavy construction vehicle used to compact soil, gravel, or asphalt during the construction of roads and other surfaces. It typically features a large, cylindrical drum that rolls over the material, applying pressure to create a smooth and stable surface. Road rollers come in various types, including static, vibratory, and pneumatic, each designed for specific tasks. These machines are essential in the construction industry, ensuring that roads are durable and can withstand traffic loads. They are often used in conjunction with other equipment, such as excavators and bulldozers, to prepare and finish road surfaces efficiently.
