What distinguishes the assembly joint with seal - plank from other joint types?

The assembly joint with seal - plank is specifically designed to facilitate movement while still providing structural support. This joint allows for slight movements that occur due to temperature changes, traffic loads, or other environmental factors, making it particularly effective for bridges where dynamic loads are a consideration. The ability to support loads while accommodating movement is crucial in ensuring the longevity and safety of the bridge structure.

This characteristic differentiates it from other joint types that may either restrict movement or not provide adequate load support. For instance, some joints are rigid and do not allow movement, which can lead to stress and potential damage to the bridge over time. On the other hand, joints that consist of elastic materials may allow movement but might not be designed to support significant loads effectively. Lastly, durability is an important factor in joint selection, but it doesn’t specifically relate to the unique function and design philosophy of the assembly joint with seal - plank. Hence, its capacity to support loads while allowing movement is what sets it apart as the distinct choice in this context.
