Warm-Mix Asphalt and Reclaimed Asphalt Pavements What the Public Should Know
According to the 10th annual survey, the industry reclaimed 97 million tons of reclaimed asphalt pavement (RAP) for future use, saving about 58.9 million cubic yards, or enough landfill space to fill up the dome of the U.S. Capitol 1,223 times. This massive reclamation effort also saved $5.3 billion in gate fees for disposal in landfills. Above recycling, the use of RAP and WMA (warm-mix asphalt) in asphalt mixtures leads to quantifiable reductions in GHG emissions.
Cumulatively for the period 2009-2019, the use of RAP is estimated to have eliminated 21.2 million tonne CO2e, equivalent to the average annual emissions from approximately 460,000 passenger vehicles, while GHG emissions reductions from the use of WMA is estimated to between .642 and 2.58 million tonne CO2e, equivalent to annual emissions between of 14,000 to 56,000 passenger vehicles.
