Quick Summary

Earthwork refers to any construction made of earth. This can include raised banks or walls, often seen in prehistoric structures. It also encompasses the operations involved in moving and shaping earth, such as excavations and embankments.12

In road construction, earthwork is a crucial initial step. After surveyors define the road's path, the existing ground is shaped, and drainage systems are installed. Imported materials are then added and compacted using rollers. Machines like bulldozers, graders, and excavating machines are vital for clearing land, moving soil, and shaping the terrain for construction projects.345
