What your plans must show

Plan Content Requirements for this index — the SPI's checklist for designers.

• Show Strip Seal Expansion Joints on Superstructure and Approach Slab detail sheets and other sheets as required. Label Expansion Joint by name or Index number. Show Sidewalk Cover Plates at all expansion joint locations that intersect with sidewalks. Complete the "Strip Seal Expansion Joint Data Table Index 458
• - 100" using the instructions provided and include the table in the plans. See FDM 115 for more information regarding use of Data Tables. Instructions:
• 1. Total Design Movement is the absolute value of the total factored temperature movement (expansion and contraction), measured in the direction of movement. Use Figures 1 through 4, for determining the Direction of Movement.
• 2. Include a value for Dimension A in the Data Table. Dimension A (measured perpendicular to the joint) @ 70°F is normally set at 2 inches to accommodate installation of the joint seal and a total design movement up to 3 inches. Set Dimension A to account for skews or greater design movements while meeting the design limitations below:
• a. the minimum factored joint opening in the Direction of Movement is ½ inch for concrete superstructures and 1” for steel superstructures ;
• b. the maximum factored joint opening in the Direction of Travel ("W" per SDG 6.4) is 4 inches;
• 3. Dimension A adjustments for 10°F shall be based on the unfactored movements perpendicular to the centerline of the joint.
