Apparatus, system and method for directional degradation of a paved surface
View Patent ↗An apparatus, system and method for directionally degrading a paved surface. A substantially cylindrical rotary tool may include cutting inserts embedded within its cylindrical surface. The tool may be rotated about a rotational axis extending from a top end of the tool to its cutting head and may contact a paved surface such that the tool degrades the surface in a direction substantially normal thereto. The tool may be mounted to a motorized vehicle and adapted for independent movement to limit degradation to an isolated area, extend degradation beyond the width of the motorized vehicle, and/or avoid obstacles in the pavement.
1. An apparatus for directional degradation of a paved surface, comprising:
an attachment assembly connected to a motorized vehicle comprising a plurality degradation tools; at least two of the degradation tools comprising a substantially cylindrical rotary element having a cutting head, a top end, and a substantially cylindrical surface, the substantially cylindrical surface formed about a rotational axis longitudinally extending from the cutting head to the top end, wherein the substantially cylindrical rotary element is adapted to rotate about the rotational axis; and
a plurality of cutting inserts embedded within the substantially cylindrical surface and adapted to degrade a paved surface in a direction substantially normal to the rotational axis;
the at least two degradation tools being adapted for at least one of independent and collective movement relative to the attachment assembly.
2. The apparatus of claim 1 , further comprising a central bore substantially corresponding to the rotational axis, the central bore adapted to apply rejuvenation materials to the paved surface.
3. The apparatus of claim 1 , wherein the cutting head comprises at least one plunging element adapted to impact the paved surface.
4. The apparatus of claim 1 , wherein the top end comprises an annular recess adapted to direct degraded pavement particles away from the plurality of cutting inserts.
5. The apparatus of claim 1 , wherein the plurality of cutting inserts comprises a substrate bonded to a cutting material.
6. The apparatus of claim 5 , wherein the cutting material is selected from the group consisting of polycrystalline diamond and cubic boron nitride.
7. A system for directional degradation of a paved surface, comprising:
a motorized vehicle comprising an attachment assembly; and
at least one degradation tool coupled to the attachment assembly and adapted for independent movement relative thereto, the at least one degradation tool comprising a top end, a cutting head and a cylindrical surface, wherein a plurality of cutting inserts are embedded within the cylindrical surface and wherein the at least one degradation tool is adapted to degrade a paved surface in a direction substantially normal to its axis of rotation;
at least two of the degradation tools are adapted for at least one of independent and collective movement relative to the attachment assembly.
8. The system of claim 7 , wherein the motorized vehicle is selected from the group consisting of a tractor, a loader, a backhoe, a road grader, a bulldozer, and an excavator.
9. The system of claim 7 , wherein the attachment assembly comprises a mounting member extendable beyond a width of the motorized vehicle.
10. The system of claim 7 , wherein the at least two degradation tools further comprises an actuating mechanism adapted to actuate the at least two degradation tools in a direction independent of the motorized vehicle.
11. The system of claim 10 , wherein the actuating mechanism actuates the at least two degradation tools in at least one of a horizontal, vertical, transverse, diagonal and pivotal direction relative to the motorized vehicle.
12. The system of claim 10 , further comprising a control device operatively coupled to the actuating mechanism to control the direction of the at least two degradation tools.
13. The system of claim 12 , wherein the control device comprises at least one of an automated feedback system and a manually operated system.
14. The system of claim 7 , the plurality of cutting elements comprising a substrate bonded to a cutting material, the cutting material selected from the group consisting of polycrystalline diamond and cubic boron nitride.
15. The system of claim 7 , the at least two degradation tools further comprising at least one plunging element integral to the cutting head.
16. A method for directionally degrading a paved surface, comprising:
providing at least two degradation tools, each have a top end, a cutting head, and a substantially cylindrical surface;
coupling to the substantially cylindrical surface a plurality of cutting inserts;
rotating the at least two degradation tools about a rotational axis substantially normal to a paved surface;
contacting the paved surface with the at least two degradation tools to degrade the same; and
moving independent or collectively the at least two degradation tools relative to each other.
17. The method of claim 16 , further comprising:
providing a motorized vehicle to traverse the paved surface;
coupling to the motorized vehicle the at least two degradation tools; and
actuating the at least two degradation tools in a direction independent of the motorized vehicle.
18. The method of claim 17 , wherein actuating the at least two degradation tools in a direction independent of the motorized vehicle comprises actuating the at least two degradation tools in at least one of a horizontal, vertical, transverse, diagonal and pivotal direction relative to the motorized vehicle.
