  • 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 [2][3]. 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.
