This report provides a summary of the sustainability efforts of the Illinois Department of Transportation (IDOT) in recycling reclaimed materials in highway construction during calendar year 2015. This report meets the requirements of Illinois Public Act 097-0314 by documenting IDOT’s efforts to reduce the carbon footprint and achieve cost savings through the use of recycled materials in asphalt paving projects. Research efforts undertaken and those that will have a future impact on IDOT’s sustainability efforts are also highlighted. In 2015, 2,009,972 tons of reclaimed or recycled materials, valued at $59,715,613, were used in Illinois highways. It was estimated that the substitution of virgin materials with reclaimed and recycled materials resulted in a net reduction of carbon dioxide emissions of 132,247 tons. |
