Pavement trimming tool
View Patent ↗An apparatus for degrading the periphery of a paved surface is disclosed in one aspect of the invention as including a support assembly, one or more pavement degradation tools coupled to the support assembly and adapted to degrade a paved surface, and a trimming tool coupled to the support assembly and adapted to degrade the edge created by the pavement degradation tools, thereby providing a desired contour to the edge. In selected embodiments, the trimming tool is adapted to straighten the edge created by the pavement degradation tools. The support assembly may be connected to a vehicle and adapted to laterally extend and retract the trimming tool with respect to the vehicle.
1. An apparatus for degrading the periphery of a paved surface, the apparatus comprising:
a support assembly;
at least one pavement degradation tool coupled to the support assembly, the at least one pavement degradation tool adapted to degrade a paved surface, thereby creating an edge; and
a trimming tool coupled to the support assembly, the trimming tool adapted to degrade the edge to provide a desired contour to the edge wherein the at least one pavement degradation tool comprises is independently movable with respect to the trimming tool.
2. The apparatus of claim 1 , wherein the trimming tool is adapted to straighten the edge created by the at least one pavement degradation tool.
3. The apparatus of claim 1 , wherein the at least one pavement degradation tool comprises an array of pavement degradation tools.
4. The apparatus of claim 1 , wherein the at least one pavement degradation tool is adapted to oscillate independent of the trimming tool.
5. The apparatus of claim 1 , wherein the trimming tool is characterized by an axis of rotation, the trimming tool adapted to degrade the edge in a direction substantially normal to its axis of rotation.
6. The apparatus of claim 1 , wherein the trimming tool is adapted for at least one of perpendicular, lateral, and rotational movement relative to the support assembly.
7. The apparatus of claim 1 , wherein:
the support assembly is connected to a vehicle; and
the support assembly is adapted to laterally extend the trimming tool with respect to the vehicle.
8. The apparatus of claim 1 , wherein the support assembly comprises at least one hydraulic cylinder to move at least one of the pavement degradation tool and the trimming tool with respect to the vehicle.
9. The apparatus of claim 1 , where the pavement trimming tool comprises:
a tool body having an outer circumference; and
a plurality of degradation inserts coupled to the outer circumference, the degradation inserts including a material selected from the group consisting of natural diamond, synthetic diamond, polycrystalline diamond, and cubic boron nitride.
10. A system for degrading the periphery of a paved surface, the system comprising:
a vehicle;
at least one pavement degradation tool coupled to the vehicle, the at least one pavement degradation tool adapted to degrade a paved surface, thereby creating an edge; and
a trimming tool coupled to the vehicle, the trimming tool adapted to degrade the edge to provide a desired contour to the edge wherein the at least one pavement degradation tool comprises is independently movable with respect to the trimming tool.
11. The system of claim 10 , wherein the trimming tool is adapted to straighten the edge created by the at least one pavement degradation tool.
12. The system of claim 10 , wherein the at least one pavement degradation tool comprises an array of pavement degradation tools.
13. The system of claim 10 , wherein the at least one pavement degradation tool is adapted to oscillate independent of the trimming tool.
14. The system of claim 10 , wherein the trimming tool is characterized by an axis of rotation, the trimming tool adapted to degrade the edge in a direction substantially normal to its axis of rotation.
15. The system of claim 10 , wherein the trimming tool is adapted for at least one of perpendicular, lateral, and rotational movement relative to the vehicle.
16. The system of claim 10 , further comprising a support assembly coupling the trimming tool to the vehicle.
17. The system of claim 10 , wherein the support assembly comprises at least one hydraulic cylinder to move the trimming tool with respect to the vehicle.
18. The system of claim 10 , where the pavement trimming tool comprises:
a tool body having an outer circumference; and
a plurality of degradation inserts coupled to the outer circumference, the degradation inserts including a material selected from the group consisting of natural diamond, synthetic diamond, polycrystalline diamond, and cubic boron nitride.
