What type of surface finishing follows rough grading?

• A. Coarse grading
• B. Fine grading
• C. Topping
• D. Base grading

Answer: (B)

Fine grading is the process that follows rough grading in the preparation of a site for construction or other land use. After rough grading has established the general contours and elevations of the site, fine grading focuses on creating a level and properly shaped surface that meets specific design requirements. This process typically involves the removal of small imperfections, such as bumps and depressions, and ensures that the surface is smooth and ready for the next steps, which can include the installation of pavement, landscaping, or other surface improvements. Fine grading is essential for achieving the desired finish, allowing for proper drainage and aesthetic appeal. The other options represent distinct grading phases or techniques that do not directly follow rough grading. Coarse grading is often associated with the initial leveling and shaping of the ground, while base grading may refer to the preparation of a base layer for construction. Topping refers to the application of a surface treatment or final layer, which occurs after the fine grading phase.
