• Abstract:
  Together, VTrans and VTANR-DEC are working to develop the use of Recycled Asphalt Shingles (RAS) as an aggregate additive to gravel roads. The idea for this project stemmed from a 2002 pilot of a RAP/RAS/Gravel used by Vermont towns in 2002 1. Available literature from Minnesota DOT (2014) and Iowa DOT (1997) show the beneficial use of RAS in gravel roads, providing reduced maintenance needs and decreased dust 23. Vermont generates an estimated 25,000 tons of waste shingles a year 4. Act 175 of the Vermont Legislature will increase shingle recycling, and create a supply of RAS in the state. To utilize this supply of RAS, VTrans and VTANR-DEC are advocating and testing the use of 20% RAS in town gravel roads. The proposed projects targeted using RAS that meets AASHTO MP-23, which calls for material 3/8” minus (100% of material passing a 3/8” sieve), with limited debris.
