Fixing US infrastructure

In a hearing this month before the US House of Representatives Subcommittee on Research and Technology of the Committee on Science, Space, and Technology, Representative Daniel Lipinski said: “As we make plans to shore up our infrastructure and build for the future, we must take advantage of all the tools at our disposal.”

“This includes using innovative technologies and emerging materials where they offer the best value for a project. Materials, such as fibre reinforced polymer composites, or advanced composites, may play a key role in how the nation addresses its challenges under constrained resources.”

Composite Advantage, a leading supplier of FRP products for bridges, waterfront infrastructure and rail platforms, says composite products are playing an increasingly important role in US infrastructure applications.

The company’s FiberSPAN FRP bridges and bridge decks have found a strong market niche in the trail bridge arena due to the material characteristics of its products. “Because bridge deck panels don’t corrode, there is zero maintenance, giving its products a life cycle of 100 years. The cost savings that result from eliminating upkeep has gained the attention of groups like the RTC,” the manufacturer explains.

Trails Transform America

This year, the US administration unveiled a plan for fixing the nation’s infrastructure. In 2020, federal transportation legislation will come due for renewal. The Rails-to-Trails Conservancy has deemed the timing right and formed a Trails Transform America campaign to ask Congress and the White House to include trails, walking and biking in the final infrastructure bill.

Headquartered in Washington, DC, Rails-to-Trails Conservancy (RTC) believes that for communities to thrive, urban, suburban and rural trail networks are essential. These networks are giving communities access to “healthy outdoor mobility choices that save money, free up road space, reduce pollution and health-care costs and promote economic vitality.”

The drive to extend the reach of trail networks dovetails nicely with the composite industry’s push to also include fibre reinforced polymer (FRP) bridge and bridge deck products in the proposed legislation. In February, members of the American Composites Manufacturers Association (ACMA) met with elected officials, staff members and one of the architects of the Infrastructure Plan to talk about the value of advanced materials.

FRP composites

FRP composites are an engineered material. Polymers support and protect high-strength fibre reinforcements from corrosion and the effects of environmental factors such as salt water, deicing chemicals, oils, acids and UV radiation. One of the oldest FRP trail bridges was installed in 1996 on a bicycle path in Ohio, where it has been exposed to snow, ice and cold temperatures for more than two decades. Regular inspections have found the structure damage free.

“The need to shave long-term costs has decision makers listening up and down the supply chain. A closer look at a major project shows the broad scope of influence wielded by the RTC,” the company says. “The Industrial Heartland Trails Coalition wants to establish the Industrial Heartland as a premier destination offering a 1,500-miles-plus multiuse trail network experience.”
