What is the role of the road grader in road construction planning?

• A. To compact soil for stability
• B. To provide necessary topographical adjustments for construction
• C. To transport materials to the site
• D. To level the completed road surface

Answer: (B)

The role of the road grader in road construction planning is crucial for shaping and preparing the terrain where a road will be built. The grader's primary function is to create the necessary topographical adjustments, ensuring that the surface is graded to the correct slope and elevation. This involves removing high spots and filling in low areas, which establishes a stable foundation for the subsequent layers of road material. Proper grading is essential for effective drainage, which helps prevent erosion and flooding, and also contributes to the overall safety and longevity of the roadway. By making these adjustments early in the construction process, the road grader facilitates better alignment and design of the road according to engineering specifications. This is fundamental before any further construction activities, such as paving, can take place, making the grader an essential piece of equipment in the planning and execution of road construction.
