2 - Loads and Load Factors |

## 2.2 Dead Loads (01/09) 2009 Jan: Revised per TDB C08-05. 2008 Jan: Added paragraph C.

A. Future Wearing Surface: See Table 2.1
regarding the allowance for a Future Wearing Surface.

B. Sacrificial Concrete: Bridge decks subject to the profilograph requirements of Chapter 4
require an added thickness of sacrificial concrete, which must be accounted for as added Dead Load but cannot be utilized for bridge deck section properties.

C. Stay-in-Place Forms: Design all beam and girder superstructures (except segmental box girder superstructures) to include the weight of stay-in-place metal forms, where permitted. For clear spans between beams or girders greater than 14 feet, verify the availability of non-cellular forms and include any additional dead load allowance greater than 20 psf or specify the use of cellular forms (where permitted) or non-cellular forms with cover sheets.

D. See SDG 2.5 Miscellaneous Loads
for common component dead loads.
