Reclaimed Asphalt Pavement (RAP) in Asphalt Mixtures: State-of-the . . . In the early 1990s, FHWA and the U S Environmental Protection Agency estimated that more than 90 million tons of asphalt pavement were reclaimed (i e , converted into material suited for use) every year, and over 80 percent of RAP was recycled, making asphalt the most frequently recycled material (2) RAP is most commonly used as an aggregate
Reclaimed Asphalt Pavement - User Guideline - Asphalt Concrete (Hot . . . Reclaimed asphalt pavement (RAP) can be used as an aggregate in the hot recycling of asphalt paving mixtures in one of two ways The most common method (conventional recycled hot mix) involves a process in which RAP is combined with virgin aggregate and new asphalt cement in a central mixing plant to produce new hot mix paving mixtures
RAP Benefits for Pavement Owners - National Asphalt Pavement Association HOW AND WHERE IS RAP RECYCLED? nstruction in the United States As a fully recyclable product, RAP has many applications, and can be used over and over again, reducing the eed for costly virgin materials More than 94% of RAP is used in new asphalt mixtures, while a small percentage is incorporated into other civil engineering applicati
Recycling Asphalt Pavements: - University of Connecticut For a particular roadway, which material is better environmentally, economically: e g , recycled or virgin? Will changing the recycled material content in a particular pavement affect its environmental performance? Does sending demolished portions of a road to a processing plant or to a landfill make more environmental and economic sense?
Asphalt Pavement Industry Survey on Recycled Materials and Warm-Mix . . . The objective of this survey, first conducted for the 2009 and 2010 construction seasons, was to quantify the use of recycled materials, primarily RAP and RAS, as well as the use of WMA technologies by the asphalt pavement industry
PennDOT RECYCLING MATERIAL FACT SHEET Reclaimed Asphalt Pavement (RAP) Asphalt pavement is America’s most recycled and reused material A recent FHWA survey reported that asphalt pavement recycled and reused rate is approximately 99 percent for W , approximately 6 4 million tons of RAP was used as aggregate, and approximately 110 3 mi
Asphalt Pavement Recycling with Reclaimed Asphalt Pavement (RAP) As part of the FHWA recycled materials policy, the FHWA actively promotes asphalt pavement recycling and technology There are three key requirements that must be satisfied for asphalt pavement recycling to be successful Recycled asphalt pavements must: perform well
Recycling - National Asphalt Pavement Association 94 6 Million Tons The amount of reclaimed asphalt pavement (RAP) recycled into new mixes in 2021—an 8 74% increase over the previous year 95% The percentage of asphalt mixture reclaimed from old asphalt pavements and put back to use in new pavements in 2021—up from 93% the previous year
