What type of deck would typically require less maintenance due to its structural design?

A stress laminated deck typically requires less maintenance due to its structural design and the materials involved. This type of deck is constructed using timber elements that are laminated together under high compression, which enhances their performance characteristics. The compression generated in the laminating process helps to minimize the effects of moisture fluctuations and reduces the likelihood of checking and splitting, common issues with timber structures.

Additionally, stress laminated decks are often designed to have improved resistance to deformation and cracking, which can lead to a longer service life with reduced maintenance needs. The effective load distribution across the laminated elements further adds to the structural integrity and durability of the deck, making it a practical choice for long-term sustainability in bridge applications.

In contrast, nail laminated decks, plan decks, and timber decks may experience more wear and require more frequent inspections and maintenance due to their design and material properties, which may not provide the same level of durability and resistance to environmental factors.
