Minor rail damage: Repair spalls in accordance with Section 1 (epoxy mortar) or Section 2 (proprietary, bagged concrete repair materials) of Chapter 3 in this manual. Seal cracks in accordance with Section 6 (gravity-fed sealant) or Section 7 (surface seal) of Chapter 3. Touch up any scrapes or other minor damage to steel elements in accordance with standard District maintenance practices. If any galvanized elements are impacted, then the Engineer should evaluate to determine appropriate repair procedures, such as touch-up using zinc-rich paint or other process. See Item 445, “Galvanizing” and the Department Material Producer List for Galvanizing Repair Paints for more information.

Intermediate rail damage: Repair spalls in accordance with (proprietary, bagged concrete repair materials) or (batched concrete) of Chapter 3. Ensure there is a mechanical bond by completely excavating around exposed reinforcing steel.

Major rail damage: When damage is severe enough to reduce the structural capacity of a rail, the best option for full restoration is to remove the rail to the level of the concrete deck and retrofit in accordance with the TxDOT Bridge Standards Retrofit Guide for concrete rails or curbed structures. All damaged components should be replaced or supplemented, and structural class batched concrete should be used to cast the new section of concrete railing.

If the Engineer determines that major rail damage can be repaired rather than retrofitted to sufficiently restore capacity, perform work in accordance with , “Concrete Rail Repair.” When feasible, utilize batched concrete rather than proprietary, bagged material to repair the damaged rail.

Installation of new anchors and reinforcement is critical to ensuring adequate capacity of the concrete railing and steel-mounted components. When using an adhesive to anchor steel bars, install in accordance with , “Railing.” Note that anchorage testing of installed adhesive anchorages may be required as directed by the Engineer.
