Motor graders are the main machinery used for shaping and leveling operations in earthwork, and are widely used in large-area ground leveling operations such as highways and airports. The reason why the grader has a wide range of auxiliary work capabilities is that its moldboard can complete 6 degrees of movement in space. They can be carried out individually or in combination. The grader can provide sufficient strength and stability for the roadbed in the construction of the roadbed. Its main methods in subgrade construction are leveling, slope brushing, and embankment filling.
A motor grader is a high-speed, high-efficiency, high-precision and multi-purpose earthmoving machinery. It can complete large-scale ground leveling and ditching, scraping, bulldozing, snow removal, loosening, compaction, cloth, mixing, auxiliary equipment and wasteland reclamation for large areas such as highway important content fields and farmland. It is an important equipment in the construction of national defense engineering, mine construction, road construction, water conservancy construction and farmland improvement. The roadbed is the foundation of the road surface and an important part of highway engineering. The roadbed bears the traffic load from the road surface and is the supporting structure of the road surface. It must have sufficient strength, stability and durability. Depending on the terrain, highway subgrades generally take the form of embankments and cuttings.
