After about a year of testing, NITROcrete is now approved by the Virginia Department of Transportation for safe use in concrete roadwork operations. With this, VDOT brings concrete cooling into the 21st century as an alternative to ice cooling.

With all due diligence, VDOT and NITROcrete engineering, along with industry partners in the region, collaborated to conduct rigorous testing to compare NITROcrete with ice cooling methods. The result? NITROcrete passed all necessary VDOT testing, proving once again that automated liquid nitrogen is an effective alternative to the hassles of ice cooling.

“This team effort was monumental,” VP of Engineering Eric Van Dixhorn said. “We’ve been working on this since last summer,” he added. Particularly, Van Dixhorn pointed to concrete materials engineer Cameron Wilson as a key asset to ensuring that the hard work of rigorous testing remained on track.

Virginia joins several other US Departments of Transportation in approving the use of NITROcrete for concrete temperature control. With obvious cost benefits from batching while cooling, achieving rigorous specifications more reliably and easily compared to ice, NITROcrete offers Virginia road work operations a way forward for safer communities and highways.
