Question: An operator is using a compact track loader to grade a permeable gravel driveway. To achieve proper compaction and maintain the permeable qualities, what is the recommended final grading technique?

Answer options:

• Using maximum down pressure on the bucket in a pushing motion to consolidate the gravel. ✅ Making light, even passes with the cutting edge slightly above the target grade, allowing the tracks to gently compact and level.
• Rapidly oscillating the bucket and travel speed to create an uneven, interlocking surface.
• Applying a thick layer of fine aggregate as a topcoat and then compacting heavily.

Correct answer: Making light, even passes with the cutting edge slightly above the target grade, allowing the tracks to gently compact and level.

Explanation: For permeable surfaces like gravel driveways, light, even passes with the cutting edge slightly above the grade, allowing the machine's weight and tracks to provide gentle compaction and leveling, helps maintain permeability while achieving the desired grade. Excessive down pressure can over-compact and hinder water flow.
