What is excavation in a road construction?

Excavation in road construction refers to the process of removing earth, rock, or other materials from a site to create a foundation for the road. This involves digging trenches or pits to achieve the desired depth and grade, ensuring proper drainage and structural integrity. Excavation is essential for laying down subbase materials and utilities, and it helps prepare the area for subsequent roadway layers. Effective excavation practices also minimize environmental impact and ensure safety during construction.
