Abstract

A joint density assembly adapted for use on a screed comprising an endgate having a vertical axis, a frame mounted to the screed, a mounting means adapted to mount the frame to the screed, and a fixed shoe, a bolt-on unit mounted to the screed and disposed between the screed and the endgate, and a means for adjusting the bolt-on unit between a downward position and an upward position. A method for increasing the density of an asphalt longitudinal joint comprising providing a joint density assembly and adjusting the bolt-on unit.

Claims (36)

1. A joint density assembly adapted for use on a screed, said joint density assembly comprising:

(a) an endgate, said endgate having a vertical axis and comprising:

(1) a frame, said frame being mounted to the screed;

(2) a mounting means, said mounting means being adapted to mount the frame to the screed;

(3) a fixed shoe;

(4) a pivoting shoe, said pivoting shoe being disposed in front of the fixed shoe;

(b) a bolt-on unit, said bolt-on unit being mounted to the screed;

(c) a means for adjusting the bolt-on unit, said means for adjusting the bolt-on unit being adapted to adjust the bolt-on unit between a downward position and an upward position;

wherein the bolt-on unit is disposed between the screed and the endgate.

2. The joint density assembly of claim 1 wherein the assembly is removably mounted on the screed.

3. The joint density assembly of claim 1 wherein the mounting means comprises a threaded fastener.

4. The joint density assembly of claim 1 wherein the bolt-on unit is pivotally mounted to the screed.

5. The joint density assembly of claim 1 wherein the means for adjusting the bolt-on unit comprises a jack screw.

6. The joint density assembly of claim 1 wherein the bolt-on unit is adapted to be independently adjusted.

7. The joint density assembly of claim 1 wherein the bolt-on unit has an angle of attack that is adapted to be adjusted.

8. The joint density assembly of claim 1 wherein the bolt-on unit is adapted to be adjusted to allow more asphaltic material into an asphalt longitudinal joint.

9. The joint density assembly of claim 1 wherein the bolt-on unit is adapted to increase an asphalt longitudinal joint density.

10. The joint density assembly of claim 1 wherein the endgate further comprises a hold-down assembly.

11. The joint density assembly of claim 10 wherein the hold-down assembly comprises a spring.

12. The joint density assembly of claim 1 further comprising a heating element.

13. The joint density assembly of claim 1 wherein the pivoting shoe is adapted to allow more asphaltic material into an outer vertical edge of an asphalt longitudinal joint.

14. The joint density assembly of claim 1 wherein the pivoting shoe is adapted to increase an asphalt longitudinal joint density.

15. The joint density assembly of claim 1 further comprising a means for adjusting the pivoting shoe.

16. The joint density assembly of claim 1 wherein the means for adjusting the pivoting shoe comprises a jack screw.

17. A method for increasing the density of an asphalt longitudinal joint, said method comprising:

(a) providing a joint density assembly adapted for use on a screed, said joint density assembly comprising:

(1) an endgate, said endgate having a vertical axis and comprising:

(i) a frame, said frame being mounted to the screed;

(ii) a mounting means, said mounting means being adapted to mount the frame to the screed;

(iii) a fixed shoe;

(iv) a pivoting shoe, said pivoting shoe being disposed in front of the fixed shoe;

(2) a bolt-on unit, said bolt-on unit being mounted to the screed;

(3) a means for adjusting the bolt-on unit, said means for adjusting the bolt-on unit being adapted to adjust the bolt-on unit between a downward position and an upward position;

wherein the bolt-on unit is disposed between the screed and the endgate;

(b) adjusting the bolt-on unit.

18. The method of claim 17 wherein the endgate comprises a pivoting shoe and further comprising adjusting the pivoting shoe.
