Recycled Asphalt Shingles (RAS)

RAS is reclaimed asphalt shingles resulting from the processing and grinding of either pre-consumer or post-consumer shingles.

A core value of the DOT’s Strategic Plan is being environmentally responsible. Increasing the amount of recycled and reclaimed materials used in county construction projects is one way of fulfilling this effort. Public Act 097-0314 referred reclaimed asphalt shingles (RAS) as one material that could have positive environmental and economic impacts - promoting environmental awareness by reducing the amount of shingle waste being deposited in landfills and potentially reducing the cost of HMA mixtures in transportation projects.
