Abstract

A dowel includes a corrosion-resistant sleeve, and a rod positioned within the sleeve. A sealant connects the corrosion-resistant sleeve and the rod. A method for constructing a dowel includes positioning a rod within a corrosion-resistant sleeve, and sealing the rod with respect to the corrosion-resistant sleeve.

Claims

1. A dowel comprising:

a corrosion-resistant sleeve;

a rod positioned within the corrosion-resistant sleeve, the ends of the rod within the ends of the sleeve; and

a sealant positioned between the outer portion of the rod and the inner portion of the corrosion-resistant sleeve.

2. The dowel of claim 1 wherein the corrosion-resistant sleeve is a stainless steel sleeve.

3. The dowel of claim 1 wherein the rod positioned within the corrosion-resistant sleeve is a steel rod.

4. The dowel of claim 1 wherein the sealant connecting the corrosion-resistant sleeve and the rod.

5. The dowel of claim 4 wherein the steel rod includes a first end and a second end, and wherein the corrosion-resistant sleeve includes a first end and a second end, wherein the first end of the corrosion-resistant sleeve and the second end of the corrosion-resistant sleeve are sealed to prevent exposure of the first end of the rod within the corrosion-resistant sleeve and the second end of the rod within the corrosion-resistant sleeve.

6. The dowel of claim 5 wherein the sealant includes silicone.

7. The dowel of claim 5 wherein the sealant includes an adhesive.

8. The dowel of claim 1 wherein the dowel further comprises a coating on the rod, the coating substantially sealing the rod with respect to the corrosion-resistant sleeve.

9. The dowel of claim 8 wherein the coating on the rod includes an epoxy.

10. The dowel of claim 8 wherein the coating on the rod and the rod are press fit into the corrosion-resistant sleeve.

11. A dowel system comprising:

a dowel further including;

a corrosion-resistant sleeve;

a rod positioned within the sleeve, the rod having a first end, a second end, and a cylindrical surface; and

a sealant for substantially sealing the first end, the second end, and the cylindrical surface of the rod within the corrosion-resistant sleeve; and

a spacer assembly associated with the dowel.

12. The dowel system of claim 11 wherein the sealant also bonds the rod within the corrosion-resistant sleeve.

13. The dowel system of claim 11 wherein the spacer assembly includes at least one spacer attached to the dowel.

14. The dowel system of claim 11 wherein the spacer assembly includes at least one spacer attached to the corrosion-resistant sleeve.

15. The dowel system of claim 11 wherein the spacer assembly is adapted to hold the dowel a selected distance from a surface.

16. The dowel system of claim 11 further comprising a plurality of dowels, the spacer assembly adapted to hold the plurality of dowels at a selected distance from a surface.

17. The dowel system of claim 11 wherein the sealant is a coating on the rod.

18. The dowel system of claim 11 wherein the sealant is an epoxy coating on the rod.

19. A roadway comprising:

a first slab of material;

a second slab of material; and

at least one dowel having a first end engaged with a first slab of material and a second end engaged with a second slab of material, the at least one dowel further comprising;

a corrosion-resistant sleeve;

a rod positioned within the sleeve, the rod having a first end, a second end, and a cylindrical surface; and

a sealant for substantially sealing the first end, the second end, and the cylindrical surface of the rod within the corrosion-resistant sleeve.

20. The roadway of claim 19 further comprising a spacer assembly associated with the at least one dowel.

21. The roadway of claim 20 further comprising a base of crushed material, the first slab of material and the second slab of material positioned adjacent the base of crushed material, the spacer assembly associated with the at least one dowel for spacing the dowel a selected distance from the base of crushed material.

22. The roadway of claim 19 further wherein the first end of the dowel is slidably engaged with the first slab and the second end of the dowel is slidably engaged with the second slab.

23. The roadway of claim 19 wherein the first slab of material and the second slab of material includes cement.

24. The roadway of claim 23 wherein the first slab of material and the second slab of material further includes aggregate.

25. A method for constructing a dowel comprising:

positioning a rod within a corrosion-resistant sleeve; and

sealing the rod with respect to the corrosion-resistant sleeve, wherein sealing the rod with respect to the corrosion-resistant sleeve includes placing a sealant on the cylindrical surface of the rod.

26. The method of claim 25 wherein sealing the rod with respect to the corrosion-resistant sleeve includes placing a sealant on the outer surface of the rod.

27. The method of claim 25 wherein the rod is substantially cylindrically shaped and wherein sealing the rod with respect to the corrosion-resistant sleeve includes placing a plurality of beads of sealant on the cylindrical surface of the rod.

28. The method of claim 27 wherein the rod is rotated.

29. The method of claim 28 wherein the rod is rotated while it is positioned within the corrosion-resistant sleeve.

30. The method of claim 28 wherein the rod is rotated after it is positioned within the corrosion-resistant sleeve.

31. The method of claim 25 wherein sealing the rod with respect to the corrosion-resistant sleeve includes placing a sealant over a first end of the rod and a second end of the rod.

32. The method of claim 25 wherein sealing the rod with respect to the corrosion-resistant sleeve includes placing a coating on the rod.

33. The method of claim 25 wherein positioning a rod within a corrosion-resistant sleeve the rod with respect to the corrosion-resistant sleeve includes press fitting a coated rod within the corrosion-resistant sleeve

34. The method of claim 25 wherein the rod is rotated.
