Tie Bar Placement

Checked against its sources by licensed professional engineers on the previous site, where reviewers weren’t recorded by name.
Tie bars are typically placed after PCC placement either by hand or using a tie bar inserter attachment (slipform paving only). When one lane at a time is paved, tie bars are inserted at mid-slab depth and bent back until the adjacent lane is ready to be paved (see Figure 1). On slipform pavers, tie bars are inserted on slab edges that will become longitudinal joints (see Figure 2 and 3) and, if two lanes at once are being paved, pushed into a mid-slab area (similar to dowel bar insertion) that will later be cut as a longitudinal joint (see Figure 4 and 5). Like dowel bars, tie bars should be protected from corrosion.
