ABSTRACT:
Apparatus for pretreating a pothole preparatory to filling thereof including determining the size and/or path of revolution of a treatment member responsive to determining the location and size of the pothole to be repaired; lowering the treatment member into the pothole; selectively revolving said treatment member and/or rotating said treatment member to abrade, compact and densify the portion of the pothole surrounding the surface thereof. Debris or other particulate in the pothole or developed by the abrading operation may be removed by a vacuum member. The pothole may be sprayed with a fluent material to either harden the surface or reduce the porosity of or render the sticky the surface of the pothole to provide a better bond between the pothole and the filler material. The force applied by the treatment member to the pothole surface is sensed and used as feedback information to control the abrading/compressing/densifying force.
