A method for the deposition of filler materials in filling and overlay applications is disclosed in which there is provided a continuous forced flow of filler material from an external reservoir, which is released through an outlet positionable over a depression in a surface which has been prepared to be filled and overlaid with filler to fill the place of application and overlay the surrounding area. An apparatus for the deposition of such filler is also disclosed.

An apparatus for repairing cracks and depressions in a paved highway surface with a fiber-and asphalt-containing filler material, said apparatus comprising, in combination, an external reservoir for providing filler material in a flowable state; outlet means receivably attached to said external reservoir for transmitting said filler material from said external reservoir; inverted saucer-shaped spreading means circumferentially surrounding and flowably receivably attached to said outlet means for applying said filler material radially outward into and over the edges of said cracks and depressions to fill the same and form an overthrust or overlayment configuration; whereby essentially random orientation of the fiber of said filler material is retained in passage of said filler material through said spreading means to provide improved shear and crack resistance to the repaired highway surface.
