Apparatus, system, and method for degrading and removing a paved surface
View Patent ↗An apparatus for degrading and removing a paved surface is disclosed in one aspect of the invention as including a vehicle to travel across a paved surface, a pavement degradation tool coupled to the vehicle and adapted to degrade the paved surface while rotating about an axis substantially normal to the paved surface, and a vacuum device coupled to the vehicle and adapted to remove pavement fragments produced by the pavement degradation tool. The vacuum device may include several intake channels to draw in the degraded pavement fragments. In selected embodiments, these intake channels may be connected to two or more independently moveable banks.
1. An apparatus for degrading and removing a paved surface, the apparatus comprising:
a vehicle for traveling across a paved surface;
a pavement degradation tool coupled to the vehicle, the pavement degradation tool adapted to degrade the paved surface while rotating about an axis substantially normal to the paved surface; and
a vacuum device comprising a plurality of independently movable intake channels is coupled to the vehicle and adapted to remove pavement fragments produced by the pavement degradation tool.
2. The apparatus of claim 1 , wherein a plurality of intake channels are divided into a plurality of banks, wherein each bank is independently moveable.
3. The apparatus of claim 1 , further comprising a shroud operably connected to the plurality of intake channels, wherein the shroud is adapted to improve the vacuum seal between the pavement fragments and the at least one intake channel.
4. The apparatus of claim 3 , wherein the shroud covers the pavement degradation tool.
5. The apparatus of claim 3 , further comprising an input channel to provide positive pressure inside the shroud.
6. The apparatus of claim 1 , wherein the vacuum device further comprises a scoop element to scoop the pavement fragments into the plurality of intake channels.
7. The apparatus of claim 1 , wherein the vacuum device comprises a roller to rotate over the pavement fragments, the roller comprising a series of vanes to direct the pavement fragments into the plurality of intake channels.
8. The apparatus of claim 1 , wherein the vacuum device comprises a bristled roller to rotate over the pavement fragments, the bristled roller adapted to brush the pavement fragments into the plurality of intake channels.
9. The apparatus of claim 1 , wherein the vacuum device comprises a separator to extract the pavement fragments fmm the air stream traveling thnzugh the plurality of intake channels.
10. A method for degrading and removing a paved surface, the method comprising:
directing a pavement degradation tool across a paved surface, the pavement degradation tool adapted to degrade the paved surface while rotating about an axis substantially normal to the paved surface; and
removing pavement fragments produced by the pavement degradation tool using a vacuum device comprising a plurality of independently movable intake channels.
