Related Article: Going Green: Finding Environmentally Friendly Boardwalk Materials. Concrete. Location. Concrete boardwalks are not a good fit for many small-scale projects, like backyard decking, a skinny walkway or a residential dock. A concrete

Engineering Insights: Pedestrian Bridge Deck Makes Business Case The arguments for composite bridge applications are compelling: rapid construction affords minimal traffic disruption; there is no metal to corrode and, thus, no long-term maintenance; and light weight allows an increase in a span's load classification, to name just three. With more than half a million bridges in the U.S. alone,

Pedestrian Bridge Surfaces - No Slipping! - Composite Advantage Mar 7, 2015 This is kind of a long way of explaining how we answer the question we first posed – can owners really get a bridge deck surface that minimizes slippage, looks good, withstands a lot of traffic and lasts a long time? The answer is yes. We've developed a hybrid system for just these types of projects. We use

Bridges Composites UK Bridge enclosures are hybrid bridge systems and are an example of an application where composites on their own would not provide the most effective solution. A system has been For suspension bridges, the aerodynamic shape and good torsional stiffness of a SPACES deck make it an attractive system. On a smaller
