Abstract

An integrated heating and comb unit and method of mechanized asphalt raking in which a mechanized asphalt comb comprised of a rake attachment and an arm is attached to an engineering vehicle via a terminating end of the arm. The engineering vehicle can control and manipulate the mechanized asphalt comb into a raised inactive position, a lowered active position, and a plurality of positions between the raised inactive position and the lowered active position. When in the lowered active position, the mechanized asphalt comb applies a fixed downward pressure and depth of penetration to the applied surface.

Claims (45)

1. An integrated asphalt heating and comb unit, the unit comprising:

a heating pan, said pan providing heat from a downward side of said pan; and

a plurality of teeth extending from said downward side in a downward orientation;

wherein said integrated asphalt heating and comb unit is attached to an engineering vehicle such that said engineering vehicle can control and manipulate said integrated unit into a raised inactive position and a lowered active position; and

wherein, when in said lowered active position, said integrated asphalt heating and comb unit applies a fixed downward pressure and depth of penetration to a surface.

2. The unit of claim 1 wherein said teeth are attached to a frame surrounding said heating pan.

3. The unit of claim 1 wherein said teeth are attached to a floating frame moveable relative to said pan and said floating frame is arranged below said downward side of said pan.

4. The unit of claim 1 , wherein at least one of said plurality of teeth is removable from said unit.

5. The unit of claim 1 further comprising: a wing support extending from said heating pan.

6. The unit of claim 5 wherein said wing support supports a propane cylinder which provides energy for at least part of said heat.

7. The unit of claim 5 wherein said wing support supports a battery which provides energy for at least part of said heat.

8. The unit of claim 7 wherein said wing support supports a propane cylinder which provides energy for at least part of said heat.

9. The unit of claim 8 further comprising at least two wing supports.

10. The unit of claim 9 further comprising a rail connecting said at least two wing supports.

11. The unit of claim 10 wherein said rail includes a control panel.

12. The unit of claim 10 wherein said rail includes a hydraulic motor.

13. The unit of claim 1 further comprising a hydraulic motor.

14. The unit of claim 1 further comprising a control panel.

15. The unit of claim 1 wherein, when said integrated asphalt heating and comb unit is used to heat asphalt, said integrated asphalt heating and comb unit is in a position between said raised inactive position and said lowered active position.

16. A mechanized method for removing and applying asphalt during an asphalt repair, the method comprising:

obtaining an integrated asphalt heating and comb unit, said unit comprising:

a heating pan, said pan providing heat from a first side of said pan; and

a plurality of teeth extending from said first side in a downward orientation;

attaching said unit to an engineering vehicle such that said engineering vehicle can control and manipulate said unit into a raised position, a lowered position, and an intermediate position between said raised position and said lowered position;

moving said engineering vehicle to an asphalt repair site with said unit in said raised position;

positioning said unit in said intermediate position;

utilizing said heating pan to heat asphalt in said asphalt repair site with said unit in said intermediate position;

without moving said engineering vehicle, positioning said unit in said lowered position where said teeth apply a fixed downward pressure and depth of penetration to a surface; and

scarifying said asphalt in said asphalt repair site with said teeth while said unit is in said lowered position.

17. The mechanized method of claim 16 , the method further comprising:

not moving said engineering vehicle while scarifying said asphalt in said asphalt repair site.

18. The mechanized method of claim 16 , the method further comprising:

moving said engineering vehicle to scarify said asphalt in said asphalt repair site.

19. The mechanized method of claim 16 , the method further comprising:

prior to said heating being completed, positioning said unit in an additional position where said teeth apply a fixed downward pressure to said surface; and

scarifying said surface.

20. A mechanized method for removing and applying asphalt during an asphalt repair, the method comprising:

obtaining an integrated asphalt heating and comb unit, said unit comprising:

a heating pan, said pan providing heat from a first side of said pan; and

a plurality of teeth extending from said first side in a downward orientation;

attaching said unit to an engineering vehicle such that said engineering vehicle can control and manipulate said unit into a raised position and a lowered position;

moving said engineering vehicle to an asphalt repair site with said unit in said raised position;

positioning said unit in said lowered position where said teeth apply a fixed downward pressure and depth of penetration to a surface;

utilizing said heating pan to heat asphalt in said asphalt repair site with said unit in said lowered position; and

scarifying said asphalt in said asphalt repair site with said teeth while said unit is in said lowered position.
