Abstract
Jointed concrete pavement is formed of concrete cured around a dowel. The dowel includes a welded seam carbon steel hollow tube and a pair of end caps. The end caps are attached to opposite axial ends of the hollow tube. The pavement comprises a fracture groove over the dowel.

A method of forming jointed concrete pavement, the method comprising:
- positioning a dowel in a location that will become concrete pavement, the dowel consisting of a carbon steel welded seam hollow tube, the end caps each comprising an opening, a fluid passageway extending through the openings of the endcaps and the carbon steel welded seam hollow tube and a pair of end caps, the end caps being attached to opposite axial ends of the hollow tube;
- allowing concrete to cure around the dowel to thereby transform the concrete into pavement;
- cutting a top surface of the pavement over the dowel.
Jointed concrete pavement comprising concrete cured around a dowel, the dowel consisting of a welded seam carbon steel hollow tube and a pair of end caps, the end caps being attached to opposite axial ends of the hollow tube, the end caps each comprising an opening such that a fluid passageway extends through the openings of the endcaps and the carbon steel welded seam hollow tube, the pavement comprising a fracture groove over the dowel.
A method of forming jointed concrete pavement, the method comprising:
- drilling a plurality of generally horizontal holes in a generally vertical face of cured concrete, the holes each have a generally cylindrical surface;
- inserting a dowel tube into each of the plurality of holes in a manner such that a portion of each of the dowel tubes extends outward from the vertical face of the cured concrete, each dowel tube having an axial passageway extending therethrough, opposite axial ends, and a cylindrical outer surface;
- pumping grout through the axial passageway of each dowel tube in a manner causing the pumped grout to at least partially fill space between the generally cylindrical surface of the holes and the cylindrical outer surfaces of the dowel tubes;
- and
- pouring concrete over the portion of the dowel tubes that extend outward from the vertical face of the cured concrete after performing the above steps.
