1. An apparatus for tilling asphalt, said apparatus comprising:
- a rotatable shaft member having a first end and a second end;
a plurality of sets of tines extending outwardly from the shaft member;
the plurality of sets of tines including a first outermost set of tines, a second outermost set of tines, and at least one set of inner tines extending outwardly from the shaft member and positioned between the first outermost set of tines and the second outermost set of tines;
wherein each of the first outermost set of tines comprises a first end interconnected to the shaft and a cutting edge on a second end that angles inwardly towards the at least one set of inner tines capable of forming a first beveled edge in the asphalt, wherein a first thickness of each of the first outermost set of tines between the first end and the second end is substantially uniform;
wherein each of the second outermost set of tines comprises a third end interconnected to the shaft and a cutting edge on a fourth end that angles inwardly towards the at least one set of inner tines capable of forming a second beveled edge in the asphalt, wherein a second thickness of each of the second outermost set of tines between the third end and the fourth end is substantially uniform;
wherein the inner sets of tines extending from the shaft member are capable of forming a substantially flat bottom surface without disrupting the beveled edges formed in the asphalt by the first outermost set of tines and the second outermost set of tines, andwherein the apparatus is capable of forming a void with uncompacted asphalt comprising the first beveled edge, the second beveled edge, and the substantially flat bottom surface between the first and second beveled edges.

Abstract
A multipurpose asphalt processor and method for repairing damaged asphalt. The asphalt processor may be used to both till and screed asphalt surfaces. The asphalt processor may include a powered shaft having a plurality of tines extending therefrom. The outermost tines on the shaft may be angled to thereby form a beveled surface along the edges of tilled area of asphalt. The asphalt processor may further include a screed for leveling tilled asphalt. The asphalt processor may take the form of an attachment for use with existing machinery, such as a tractor.
