  "description": "This crop is a detail drawing titled 'EXPANSION JOINT DETAILS' for END BENTS 1 AND 4, showing a cross-section of a preformed silicone joint seal installed at a deck expansion joint. It calls out the seal per Special Provision Section 449, silicone adhesive bonding it to the concrete faces, a filler material below meeting Georgia DOT Sub-Section 833.2.01 held with 10d galvanized nails, and key dimensions (1 3/8\" opening, 1/2\" depth, 1/4\" edge radius). No quantities or schedule data are shown in this particular crop; the linked schedule panel on the same sheet is a separate superstructure quantities table not depicted here."
