Reinforced concrete slabs are designed according to deck thickness and girder spacing. Concrete curbs, bridge railing, concrete barrier, raised medians, sidewalks, girder soffits, and slab supports are placed in conjunction with bridge slabs. Slabs may be curved, skewed, and of various widths and thicknesses.  \nThe typical slab used by the Bridge Program uses bent transverse reinforcing steel (crank bars) alternated with straight reinforcing steel and placed in conjunction with separate mats of longitudinal reinforcing steel.  \nWhen a crank bar cannot be used, the slab has separate mats of reinforcing steel, one mat in the top face and one mat in the bottom face of the slab. Each mat contains transverse and longitudinal reinforcing steel.  \nCLASS A CONCRETE shall be used for all elements. All REINFORCING STEEL in slabs, curbs, sidewalks, concrete barrier, and raised medians shall be coated.  \nLONGITUDINAL JOINTS in the slab may be required and are dependent on common screed machine widths, construction staging requirements, and/or concrete placement rate. Consideration should be given to showing longitudinal joints on bridge deck widths exceeding 50'-0\". The optional longitudinal joint should be placed at the crown if possible, otherwise it should be placed at centerline of bridge roadway.  \nTRANSVERSE JOINTS in the slab should be avoided due to their high maintenance and leakage problems. A transverse SLAB CONSTRUCTION JOINT is shown on the plans in case of a construction emergency. Depending on bridge length and concrete placement rate, transverse joints may also be required.  \n4.13-1 Rev May 2024  \nSection 4.13-Slab  \nSUPERELEVATION, CROWN, or the transverse slope of the roadway shall match that shown on Project Development Program sheets.  \nLongitudinal reinforcing steel provided in the top layer of the slab over the intermediate supports will typically be No. 6 bars spaced at approximately 7\" to 8\" . These bars will extend to the quarter point of the longer span, and shall be placed symmetrically about the centerline of the support. The top layer of longitudinal reinforcing steel in the remainder of the deck will typically be No.  \n4 bars and shall be lapped with these bars.  \nFor composite structures, longitudinal reinforcing steel will need tobe designed by the engineer.  \nFor slabs that are integral with the abutments, a bent bar is provided between the abutment and the slab. Its length is based on the following formula.  \nDISTRIBUTION REINFORCING STEEL (No.5 bars) is the longitudinal reinforcing steel placed in the bottom of the slab and is based on the following diagrams.  \n4.13-2 Rev May 2024  \nSection 4.13-Slab  \n4.13-3 Rev May 2024  \nSection 4.13-Slab  \nFor slabs that have SKEWS LESS THAN OR EQUAL TO 20 DEGREES, the transverse reinforcing steel shall be placed parallel with the substructure and dimensioned along the edge of the slab.  \nFor slabs that have SKEWS GREATER THAN 20 DEGREES, the transverse reinforcing steel shall be placed perpendicular to the centerline of the structure or to the girders.  \nFor slabs that are CURVED, the transverse reinforcing steel maybe placed perpendicular to and dimensioned along the long chord or working line, or placed radially and dimensioned along the centerline or working line of the structure. Transverse reinforcing steel may also be dimensioned along the outside edges ofthe slab. Typically, crank bars are not used with curved slabs.  \nSLAB SUPPORTS are used when a deck joint is required for bridge movement. These areas are reinforced to withstand traffic loads and tie in the anchorage system of the expansion device. Expansion devices are covered in Section 4.09-Superstructure.
