In 2009, Illinois used an estimated 284,715 tons of recycled concrete material in highway construction; IDOT spent about $3.18 million on the material for embankments, bases, and subbases

In Illinois, the innovative approach of repurposing aged concrete for highway projects is not just cost-effective but also environmentally responsible. This method reduces landfill waste while utilizing recycled concrete as a foundational element for new roads and drainage systems. With a proven history of adopting such sustainable practices, Illinois sets a commendable example for other states looking to enhance their construction methods.
