Spray Patching

Spray Patching

Spray patching is a very effective pavement maintenance treatment. It can be placed using a wand and shovelling the cover aggregate over the sprayed emulsion, but in most cases spray patching is done by using an integrated spray patching machine. The machine uses high-volume air to blow out the loose debris from the area to be patched. This is followed by an emulsion tack. The aggregate and emulsion are blended and sprayed into the pothole.
