What is the name of the road roller?
1 Answers
Road roller is called road roller. Road roller: Road roller, also known as soil compactor, is a road construction equipment. In the category of construction machinery, road rollers fall under road equipment and are widely used in large-scale projects such as high-grade highways, railways, airport runways, dams, and stadiums for filling and compaction operations. They can compact sandy, semi-cohesive, and cohesive soils, subgrade stabilized soil, and asphalt concrete pavement layers. The road roller utilizes its own gravity to perform various compaction tasks, causing permanent deformation and densification of the compacted layer. Classification of road rollers: By roller type, the roller structures include smooth drum, padfoot drum, and sheepfoot drum, etc. The smooth drum is the most commonly used, mainly for compacting the surface layer of roads. It employs mechanical or hydraulic transmission, allowing concentrated force on protruding parts, resulting in high compaction smoothness, making it suitable for asphalt pavement compaction. By axle arrangement, road rollers can be classified into single-axle single-wheel, double-axle double-wheel, double-axle triple-wheel, and triple-axle triple-wheel types. Powered by internal combustion engines, they use mechanical or hydraulic transmission. Generally, the front wheels steer for good maneuverability, while the rear wheels drive. To improve steering and compaction performance, articulated steering structures and all-wheel drive are preferred. The front wheel frame is hinged to the chassis to reduce body swing on uneven roads, while the rear wheels are rigidly connected to the chassis. Hydraulic control is used for steering via hydraulic cylinders. Both front and rear rollers are equipped with scrapers to remove adhered materials. A water spray system is also installed to sprinkle water on the rollers during asphalt pavement compaction to prevent asphalt mixture adhesion. To increase compaction force, materials like iron, sand, or water can be added inside the rollers to increase weight.
