A vertical milling apparatus for a paved surface has a rotary degradation element which has a top end connected to a carrier. The carrier is slideably attached to an underside of a motorized vehicle, and adapted to traverse the paved surface. The rotary degradation element has an axis of rotation and a plurality of inserts secured to the element's outer surface. At least one insert has a superhard working surface positioned to contact the paved surface.

What is claimed is: 1. A vertical milling assembly for a paved surface, comprising: a rotary degradation element comprising a top end connected to a carrier which is slideably attached to an underside of a motorized vehicle, and adapted to traverse the paved surface; and the rotary degradation element comprising an axis of rotation non-parallel with the paved surface and a plurality of inserts secured to the element's outer surface comprise at least one superhard working surface positioned to contact the paved surface; at least one insert comprising a superhard working surface positioned to angularly contact the paved surface at an incline; wherein the inserts are secured to a plurality of blades formed in the outer surface of the rotary degradation element and a trough is formed intermediate the blades; and wherein the rotary degradation element is also adapted to degrade the paved surface in a direction of travel of motorized vehicle. 2. The apparatus of claim 1, wherein the working surface is adapted to angularly contact the paved surface at a negative rake. 3. The apparatus of claim 2, wherein the negative rake is from 0.1째 to 60째. 4. The apparatus of claim 1, wherein the rotary degradation element is attached to the carrier by a shaft substantially coaxial with its central axis. 5. The apparatus of claim 1, wherein the rotary degradation element is adapted to degrade the paved surface in a direction substantially normal to the paved surface. 6. The apparatus of claim 1, wherein the axis of rotation is substantially perpendicular to the paved surface. 7. The apparatus of claim 1, wherein the superhard working surface is flat, rounded, chamfered, polished, or combinations there of. 8. The apparatus of claim 1, wherein the insert comprises a superhard working surface bonded to a substrate at a non-planar interface. 9. The apparatus of claim 1, wherein the superhard working surface comprises a region leached of binder-catalyzing material. 10. The apparatus of claim 1, wherein the rotary degradation element is in communication with an actuating mechanism adapted to move the rotary degradation element in an horizontal, vertical, transverse, diagonal and pivotal direction relative to the motorized vehicle. 11. The apparatus of claim 1, wherein an axis formed by at least a portion of the blade is offset from the axis of rotation by an angle from 1 to 60 degrees. 12. The apparatus of claim 11, wherein the offset tilts with or against a direction of rotation. 13. The apparatus of claim 1, wherein at least a portion of the blade is concave or convex with respect to a direction of rotation. 14. The apparatus of claim 1, wherein at least one of the inserts is positioned on an anterior side of the blade and another insert is positioned on a posterior side of the blade. 15. The apparatus of claim 1, wherein a shield comprises a first end attached to the carrier and a second end is proximate the rotary degradation element. 16. The apparatus of claim 1, wherein the rotary degradation element comprises a shape that is generally cylindrical, conical, pyramidal, rectangular, frustoconical, domed, or combinations thereof. 17. The apparatus of claim 1, wherein the trough is closed at the top end. 18. The apparatus of claim 1, wherein at least one insert is positioned in a bottom end of the rotary degradation element where a plurality of blades converge. 19. The apparatus of claim 1, wherein the superhard working surface comprises polycrystalline diamond, vapor deposition diamond, natural diamond, or cubic boron nitride. 20. A method for vertically milling a paved surface, the method comprising: providing a motorized vehicle adapted to traverse the paved surface; dislodging aggregate from the asphalt by engaging the paved surface with a plurality of inserts secured to a plurality of blades formed in an outer surface of a rotary degradation element connected to an underside of the motorized vehicle, the rotary degradation element comprising an axis of rotation substantially non-parallel to the paved surface and a plurality of troughs are formed intermediate the blades; and traversing the paved surface with the motorized vehicle such that the paved surface is substantially degraded in a direction of travel of the motorized vehicle. 21. The method of claim 20, further comprising the step of heating the asphalt prior to the step of dislodging. 22. The method of claim 20, wherein at least one insert is bonded to the rotary degradation element and comprises a superhard working surface positioned to angularly contact the paved surface at an incline. 23. The method of claim 20, wherein the method further includes a step of controlling the efficiency at which the rotary degradation elements degrade the paved surface. 24. The method of claim 23, wherein the step of controlling the efficiency includes modifying a rotational speed of the rotary degradation element, modifying a traversing speed of the motorized vehicle, modifying an incline and/or geometry of at least one insert, temperature, or combinations thereof. 25. The method of claim 20, wherein a first portion of the aggregate is removed after the step of dislodging while a second portion is left, wherein an average sized aggregate of the first portion is smaller than an average sized aggregate of the second portion.
