Finish Options

The standard finish for bridge curbing is sawn top, split face. However, in addition to these standard finishes, any of the following may be custom ordered:

  • Sawn top: most common; slabs for curb are typically sawn top and bottom; the top of the curb has a smooth finish created by saw cutting.
  • Split face: a natural face created when the slab is split on a guillotine; the resulting face of the curb has a rough finish.
  • Thermal top: fine stipple finish for aesthetic look or traction in pedestrian areas.  Slab is processed through a thermaling machine, then split or sawn into curb.
  • Sawn face: the face of the curb has a smooth finish created by saw cutting.
  • Clean back: protrusions greater than 1/4-inch are removed using hand tools to create a tighter tolerance for when pavers are abutted to curb.
  • Sawn back: provides the tightest tolerance for when pavers are abutted to curb.

Edge Detail Options

There are five basic edge details that may be specified to the exposed edges of a bridge curb:

  • Straight edge (standard).
  • Buzzed: 1/4-inch camfer (or eased) edge.
  • Rounded edge: one or both edges are chamfered and then rounded off to 1/2-inch or greater radius.
  • Chamfer: 45-degree bevel is standard, 1/2", 3/4: or 1".
  • Beveled mountable: 45-dgree chamfer is standard, up to 3" x 3" or 4" x 4", or 5" x 5".

Joint Options:

There are three basic joint options available for bridge curbing:

  • Full: a straight cut with 90-degree angles at top and bottom. Unless otherwise specified, this joint is considered standard.
  • Angled: has a cut greater than 90 degrees to allow the curb to slope downward when butted to an adjacent curb.
  • Mitered: an angled cut, top to bottom, allowing the end of one curb piece to butt into the face of another curb.
