A road roller is a mechanical device used to compact materials such as soil, asphalt and concrete. It is mainly composed of a chassis, an engine, a drive system, a road rolling system, a hydraulic system, an electrical system, etc. The main working principle of a road roller is to compact the material through the weight and vibration force of the chassis, thereby increasing the density, strength and stability of the material. According to the type and purpose of the road roller, it can be divided into single steel wheel roller, double steel wheel roller, tire roller, sit-down vibratory roller, hand-push vibratory roller, etc. Road rollers are widely used in the construction of roads, bridges, airports, ports, construction sites and other fields, and are one of the important equipment indispensable for modernization construction.
