History of RAS in pavements • Experiments started in late 70's and early 80s • First technical literature published in late 80's • On a large scale RAS have been used in the asphalt pavements for last 15 years • Two "types": -Tear-off shingles (consumer aged waste shingles) -Manufacturer waste (a.k.a. roofing shingle tabs or

Practice of including RAP and/or Recycled Asphalt Shingles (RAS) in new asphalt mixtures has increased in recent years -economic and environmental benefits • RAP has been widely used -Wearing Course: 15% -Binder Course: 20% -Base Course: 30% • RAS has emerged as a material of interest to the paving community • RAP and/or RAS are valuable components in asphalt mixtures

of asphalt pavement is a rehabilitation method that involves recycling an existing asphalt pavement and its underlying layer(s) into a new base layer. The FDR process begins with using a road reclaimer to pulverize an existing asphalt pavement and a portion of the underlying base, subbase, and/or subgrade.
