About our dowel bars. American Paving Supply manufacturers dowels bars in various diameters and lengths as specified by the purchaser. The purpose of dowel bars is to transfer loads across a joint without restricting joint movement due to thermal contraction and expansion of the concrete. To develop load transfer across a joint, dowel bars are arranged at specified intervals and at mid-depth of the pavement thickness. Dowel Bar Specifications. ASTM A Grade 60 Steel. Other steel grades available upon request. Coating Options Available. Epoxy coating. Dowel bars Dowel bars are placed at the transverse joints of concrete pavement and they take part in partial wheel load transfer from one slab to its adjacent slab. The dowel bars also allow axial thermal expansion and contraction of the concrete slab along the axis of the dowel. Tie bars Tie bars are deformed rebars   Difference between dowel bars and tie bars. 5Oct Sep Add a comment. Dowel bars. Dowel bars are placed at the transverse joints of concrete pavement and they take part in partial wheel load transfer from one slab to its adjacent slab. The dowel bars also allow axial thermal expansion and contraction of the concrete slab along the axis of the dowel. Tie bars. A dowel bar Galvanized Dowel Bars retrofit (DBR) is a method of reinforcing cracks in highway pavement by inserting steel dowel bars in slots cut across the cracks. It is a technique which several U.S. states' departments of transportation have successfully used in repairs to address faulting in older jointed plain concrete pavements. The typical approach is to saw cut and jackhammer out the slots for the dowels. Following dowel placement the slots are then typically backfilled with a non-shrink concrete mixture, and the. Prior to the application of the concrete floors, the points of dowel bar application are determined. Epoxy-Coated Dowel Bars protect by using various mechanisms. Information Form. Dowels are saw cut to customized length. Figure 3 shows typical coating of dowel bars bar locations at a transverse construction joint.

Product Overview Description Dowel bars provide a mechanical connection between slabs without restricting horizontal joint movement.

Uses Inserted at mid-slab depth to help transfer load but allow adjacent slabs to expand and contract independent of one another Features Saw cut Epoxy Coating.

As Regbar, we offer the best products, services and support that best fit to your needs of Dowel Bar. We produce epoxy coated, galvanized, stainless Dowel Bars. Dowel Bars are placed in the transverse joints of the concrete floor and they play a part in the transfer of partial shear load from a floor to adjacent floor. Dowel Bar also allows axial thermal expansion and contraction of the concrete slab along the shear axis.

Half of the length of this bar is embedded in one of the concrete slabs and the rest is adhered to the adjacent slab. One end of the rod is kept free for movement during expansion and contraction of the slab depending on temperature change. Dowel Bar is used to transfer the load from one Gfrp Dowel Bars slab to other, while allowing axial thermal expansion along the shaft axis. Stainless Dowel Bar is usually made of flat round material.

They offer a corrosion-resistant solution that is resistant to connections in concrete or other structural applications. This reduces joint deflection and stress in the approach and leave slabs.

Figure 1. Typical dowel bar location on transverse joints Dowel bars are typically 32 to 38 mm 1. Specific locations and numbers vary by state, Dowels Bars however a typical arrangement might look like Figure 1. In order to prevent corrosion, dowel bars are either coated with stainless steel Figure 2 or epoxy Figure 3. Dowel bars are usually inserted at mid-slab depth and coated with a bond-breaking substance to prevent bonding to the PCC.

Thus, the dowels help transfer load but allow adjacent slabs to expand and contract independent of one another.
