What's Happening?
The Minnesota Department of Transportation (MnDOT) is undertaking over 200 road and bridge projects this summer, emphasizing the reuse of construction materials. According to Curt Turgeon, MnDOT's director of the office of materials and road research,
the industry prefers the term 'recycled' over 'waste' for materials like asphalt, concrete, and steel. The Environmental Protection Agency reports that about 95% of asphalt concrete waste is reused. Contractors are responsible for finding cost-effective ways to recycle these materials, often crushing and milling them for reuse on-site or in future projects. This approach not only conserves resources but also reduces costs, as recycled materials are significantly cheaper than new ones.
Why It's Important?
The focus on recycling in road construction projects is significant for both environmental and economic reasons. By reusing materials, MnDOT reduces the demand for new resources, which helps in conserving natural resources and minimizing environmental impact. Economically, recycling materials like asphalt can save substantial amounts of money, as new asphalt is costly, heavily influenced by oil prices. This cost-saving measure benefits taxpayers and allows for more efficient use of public funds. Additionally, the practice supports sustainability goals and sets a precedent for other states to follow, potentially leading to broader adoption of recycling practices in infrastructure projects nationwide.
