The use of steel reinforced neoprene in the assembly joint with seal for planks designed to support vehicular loads is due to its combination of strength, flexibility, and durability. Steel reinforcement enhances the material’s ability to withstand significant loads and impacts associated with vehicular traffic, while neoprene itself provides excellent resistance to environmental factors such as temperature fluctuations, moisture, and chemical exposure. This combination ensures that the joints maintain their integrity and functionality over time, effectively preserving the overall structure of the bridge.

In contrast, other materials like plastic might not offer the necessary strength and durability under heavy loads. Fiberglass, while lightweight and resistant to environmental factors, does not provide the same degree of load-bearing capacity as steel reinforced neoprene. Wooden planks, on the other hand, can deteriorate or warp over time, especially when exposed to moisture and heavy traffic, leading to potential safety hazards. Therefore, the selection of steel reinforced neoprene is critical for maintaining both safety and performance in bridge construction and maintenance.
