Abstract:
Virginia Department of Transportation has recently built a unique bridge that is expected to provide long service life with minimal maintenance. The bridge is a good example of sustainability in highway infrastructure with the use of slag cement. It promotes durability through the incorporation of high-quality concrete and corrosion-resistant stainless steel reinforcement. The high strength and reduced weight of the concrete in the beams enabled long spans while lightweight aggregates in the deck concrete reduced both the weight and the potential for cracking.
