The Missouri Department of Transportation (MoDOT) has a specification that allows the use of up to 7% recycled asphalt shingles (RAS), manufacturers' or tear-off, of the total weight of the hot-mix asphalt (HMA). MoDOT has been using RAS in HMA applications since 2003. In 2005, MoDOT completed laboratory research on tear-off RAS in HMA in partnership with the Minnesota Department of Transportation and the University of Minnesota, Civil Engineering Laboratory (see Missouri Research Projects below).
