We’ve written before on the topic of asphalt sustainability, asphalt is one of the most recycled products in the United States. This recycled material can then be used for future projects.
Recycled asphalt is often referred to as reclaimed asphalt pavement or RAP. The material is removed and reprocessed from pavements that are currently undergoing reconstruction or resurfacing. The material then either undergoes a cold milling process or a full depth removal and crushing.
Large scale organizations, such as the Missouri Department of Transportation (MoDOT) use reclaimed asphalt and recycled tear-off shingles in many of their projects. The organization estimates that in 2009 they saved $20 million on resurfacing projects in which recycled asphalt was used. In addition to the substantial cost-savings, the use of reclaimed and recycled materials decreased the amount of items headed to Missouri landfills.
