Cutting the pothole into regular shape, mainly a square cube based on the pothole depth.?This will assure the vertical sides of the repair are in sound pavement. The common device is hand-held pavement saw or road cutting machines. 2. Clean the hole. Remove water and debris from the hole. 3. Pour cold mix asphalt into the hole. Keep the asphalt is about 2 inch above the surface. 4. Compact the asphalt. Use vibratory roller or plate compactor to compact the patch. 5. Finish the work and open the road.
