Which of the following is a pothole repair method mentioned?

• A. Slurry patch
• B. Full depth hot mix patch
• C. Micro-surfacing
• D. Chip seal

Answer: (B)

When repairing potholes, the goal is to restore the pavement’s structural strength by removing the damaged material and replacing it with new, well-bonded asphalt. The method that best achieves this for a pothole is full-depth hot mix patch. In this approach, you remove the full thickness of the pavement affected by the pothole, clean the base, and then place and compact hot asphalt concrete to the proper grade and compaction. This creates a solid, seamless repair that carries loads and blends with the surrounding pavement.

Other options are more surface-focused or smaller-scale fixes. A slurry patch fills potholes with a slurry mixture and is quick and cost-effective for lighter or shallower potholes, but it doesn’t replace the full depth or restore structural capacity as thoroughly. Micro-surfacing and chip seal are surface treatments intended to seal and improve the riding surface; they don’t address deep potholes or the need to restore load-carrying stiffness, so they’re not the ideal choice for a pothole requiring full-depth repair.
