Which joint is characterized by two steel anchorages and a neoprene seal?

• A. Pourable seal
• B. Cellular joint seal
• C. Compression joint seal
• D. Strip seal

Answer: (D)

Strip seal joints are designed for bridge expansion joints and are defined by steel anchorages at each side that bolt to the deck, with a continuous neoprene seal spanning the gap. The two steel anchorages hold the ends of the neoprene strip, while the elastomer provides a flexible, watertight seal as the deck moves from thermal expansion, traffic, and vibrations. This construction combines a rigid anchoring system with a flexible seal to accommodate movement while keeping out water and debris. Pourable seals use poured material, compression seals rely on a preformed elastomer pad compressed between blocks, and cellular seals use foam-filled cartridges; the distinctive setup with two steel anchors and a neoprene strip is what characterizes a strip seal.
