CHAPTER 6 Excavation, Grading, and compacted Fill 1. When we remove soil or rock, we make a cut or excavation 2. When we add soil or rock, we create a fill embankment 3. Virtually highways require earthwork to create smooth grades an alignments to provide proper surface drainage. 4. EARTHWORK is important especially in hilly areas. 6.1 Earthwork construction: 1. The fundamental objective of earthwork construction is to change the ground Surface from initial configuration to final configuration 2.
