Cold Asphalt Patch Step-by-Step: Permanent Pothole Repair in Any Weather
2026.10.30
Potholes are an emergency every road crew faces, and hot-mix plants are often closed when winter potholes appear. Cold asphalt patch is the tool that lets crews repair potholes in any weather. Here is the step-by-step.
Why cold patch instead of hot mix?
Cold patch uses specially coated aggregate that stays workable at low temperature and cures through traffic and oxidation. It needs no kettle, no hot plant, and can be applied even when it is too cold for hot asphalt.
Step-by-step pothole repair
- Clean the hole: sweep out loose gravel, mud and water. A dry, clean base bonds best.
- Remove standing water: mop or blow out water - patch over water will fail.
- Fill: pour cold patch into the hole slightly overfilled (about 1-2 cm above surface) to allow for compaction.
- Compact: tamp with a hand tamper or plate compactor; for large holes, use a small roller. Traffic can compact smaller patches.
- Check: the finished surface should sit flush with the surrounding pavement, with no loose edges.
Tips that make cold patch last
- Overfill slightly - compaction always settles the material.
- Compact the edges as much as the center to avoid feathering and raveling.
- For deep holes, patch in 5-8 cm lifts rather than one thick pour.
- Mark the patch; traffic compaction strengthens it over the first days.
