When is back blading primarily used?

• A. For excavation
• B. For finishing
• C. For grading
• D. For lifting

Answer: (B)

Back blading is primarily used for finishing operations during a grading process. This technique involves using the back of a grading blade to create a smooth, even surface after the initial grading has taken place. By reversing the blade, operators can effectively distribute and level out the material, resulting in a finer finish that is crucial for tasks such as preparing a surface for paving or establishing a reliable base for construction. The choice of back blading assists in achieving a level and clean surface finish, making it particularly useful in scenarios that require precision and a polished outcome, such as roadways and driveways. This functionality distinguishes back blading from other methods like excavation, grading, and lifting, which serve different purposes in construction and earthwork tasks.
