Jet Injection Patching

Jet Patching or jet injection patching is a pothole patching method.

Jet patching is carried out in four stages:

1. High pressure air is used to remove all debris from the pothole
2. the pothole is sealed with an asphalt emulsion to prevent water from entering the pavement subsurface
3. the aggregate is mixed with an asphalt emulsion and sprayed into the pothole at high velocity
4. finally a finer, dry aggregate is sprayed over the filled pothole to prevent the wet asphalt emulsion from adhereing to tyres until the patch has dried.
