Foam Flute Fillers are used for many bridge projects to reduce weight. This bridge project shown here is Interstate 40 over White River in Hazen, Arkansas 72064. Many bridges across the United States use foam flute fillers to be placed in the metal bridge decking or sometimes known as SIP (Stay in Place) Decking in substitute of filling them with concrete. Concrete weighs 150 lbs per cubic foot, compared to the EPS Foam used on this project, which weighed just over .9 lb per cubic foot. The new White River bridge is 3000’ long x 117’ wide and included approximately 30,000 foam fillers. The EPS Foam reduced the weight on this bridge by over 2.5 million pounds. This converts to over 1250 TONS!!
