Reclaiming, Reusing, and Recycling Asphalt Pavement
Asphalt pavement can be recycled for roadway use time and again, offering the same durability as pavements constructed with 100% virgin materials while accomplishing the following:
Asphalt Recycling
Forms of asphalt recycling date back to 1915, becoming increasingly popular in the 1970s with the development of the modern milling machine. The U.S. Environmental Protection Agency and the Federal Highway Administration estimate that we recycle more than 80 percent of the 90 million tons of asphalt pavement reclaimed each year in the US.
TxDOT promotes using RAP in many pavement management strategies. For example, the hot mix asphalt specification encourages the use of fractionated RAP while discouraging the use of unfractionated RAP. Fractionated RAP is crushed and sized reclaimed asphalt pavement that has been separated into its constituent aggregate sizes.
Uses
TxDOT uses Reclaimed Asphalt Pavement (RAP) in such construction and maintenance applications as the following:
