11. The method of patching potholes including;
-
a) preselecting an amount of patch material for loading into a rain that will under fill a pothole; b) forcible urge the patch material into, the pothole using the ram which is moveable between a retracted position and an extended position and includes a cylinder and a piston; c) measure the force on the ram as it travels from the retracted position to the extended position; d) measure the position of the cylinder relative to the top of the road surface; e) calculate the amount of patch material required to just fill the remainder of the pothole from the force, and position information; f) load the ram with an amount of patch material calculated to fill the remaining unfilled portion of the pothole; g) repeat steps b to e h) in the event the pothole is still not completely filled repeat steps e to g above.
