I've known for quite a while that the NC Dept. of Transportation does a great job taking care of our environment. I just didn't know to what extent. In reviewing the State's FY 2008-2009 Solid Waste Report, I learned some pretty interesting things about the DOT's highway construction and maintenance projects.
- Over 670,000 tons of Reclaimed Asphalt Pavement (RAP) was used as an asphalt mix additive.
- About 5,000 cubic yards of clearing and grubbing debris was used as mulch for erosion control and roadside environmental applications.
- Over 32,000 tons of coal combustion fly ash was used in concrete mixes.
- Approximately 7,500 tons of recycled glass beads were used in pavement marking.
