[0002] Pavement milling is a method of scraping off a layer of the damaged old pavement and then laying a new surface layer. Pavement milling is generally used to eliminate the loose parts of the old pavement or to ensure a good combination of the new and old surfaces.

[0003] When dealing with cracks in the road surface, first mill the existing road surface, then cut the U-shaped grooves in the concrete slab joints or cracks, clean them up and inject sealant.
