rejuvenators with reclaimed asphalt pavement (RAP) and/or recycled asphalt shingles (RAS) to create a high recycled binder. Each year, it is estimated that contractors receive about 80 million tons of asphalt In addition, approximately 11 million tons of waste asphalt shingles are generated, of which 10 million tons are from
Reclaimed asphalt pavement, commonly referred to as RAP, is made of processed materials that contained asphalt and aggregates. These materials typically come from asphalt removal during road resurfacing, construction or other related projects.
TxDOT uses Reclaimed Asphalt Pavement (RAP) in such construction and maintenance applications as the following: You can estimate the potential savings of blending RAP into asphalt pavement using this worksheet. Note: The worksheet is for informational purposes only. Actual savings will .
What is Reclaimed Asphalt Pavement (RAP)? RAP (Reclaimed Asphalt Pavement) is the material obtained after asphalt pavement is removed and pavement may be removed for various reasons including resurfacing or is therefore made up of quality aggregates coated with asphalt cement.

Recycled Asphalt Pavement (RAP) Reclaimed Asphalt Pavement in Asphalt Mixtures: State of the Practice The Federal Highway Administration has released a report that examines the state of the practice for reclaimed asphalt pavement (RAP) use in the United States as well as best practices for increasing the use of RAP in asphalt pavement mixtures.
While reclaimed asphalt pavement (RAP) is the material most often used in asphalt recycling, materials from other industries are routinely recycled into asphalt pavements instead of going into landfills. Some of the most common are rubber from used tires, glass, asphalt roofing shingles, and blast furnace slag.
In fact, according to the National Asphalt Pavement Association (NAPA) since most reclaimed asphalt is reused or recycled, asphalt pavement is recycled more than any other material and its use is growing. The amount of RAP in asphalt mixtures was million tons in 2011 and million tons in 2012.
Reclaimed asphalt pavement (RAP) is the term given to removed and/or reprocessed pavement materials containing asphalt and aggregates. These materials are generated when asphalt pavements are removed for reconstruction, resurfacing, or to obtain access to buried utilities.

Full Depth Reclamation – 'rubblizing' asphalt. The Asphalt Recycling and Reclaiming Association (ARRA) defines FDR as, "a pavement rehabilitation technique in which the full flexible pavement section and a predetermined portion of the underlying materials are uniformly crushed, pulverized or blended, resulting in a stabilized base course." FDR...
