ABSTRACT:
An oil-spreading squeegee for roadway maintenance uniformly spreads oil sprayed onto a roadway surface to be maintained or upgraded. The squeegee assures a surprisingly uniform surface, particularly by filling cracks and moderate depressions in the roadway surface not filled by mere levelling of the liquid oil after a spraying operation alone. The squeegee is towed behind the oil spraying truck, extending across the roadway surface and being maintained on rollers a selected height above the existing pavement. The squeegee pools the oil ahead of its blade while forming a uniform coating on the roadway surface over which the blade has passed. The pool of oil fills cracks and moderate depressions in the roadway surface directly, and thus avoids loss of uniformity in the height of the top of the oil coating. Aggregate is then spread over the roadway and tamped or rolled into the oil, which hardens about the aggregate to form a new, smooth roadway surface.
