Hi Kelvin.With a focus on only the repair of potholes, it has been quite sometime since I worked within a public sector highway department.
To obtain advice from the people who do such work, contact
The Town of Smithtown Highway Department, New York.
They were ahead of the process for pothole repair, somewhat like the way a
Dentist looks at repairing a deep cavity that you wish to stay fixed for more than a season.
