The Use of Recycled Asphalt Products in Asphalt Pavements

2021-7-31  Reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) are two of the most commonly used recycled materials in the world. Recommendations as to their use and handling in CT need to be made in order to increase the amount of RAP that may be introduced into the mixture and also to make determinations as to the benefits and total quantity of RAS that should be used.

Increasing the Use of Reclaimed Asphalt Pavement (RAP)

2012-10-16  The use of RAP in recycled asphalt pavements plays a critical role in creating sustainable highways. Many US highway agencies are interested in using more RAP for cost savings and the majority of State highway agency projects have the potential to use more RAP. FHWA, along with AASHTO, NAPA, and NCAT, is leading the national effort to increase RAP use responsibly and provide answers to remaining issues that have prevented increased RAP use, especially for mix design and performance. Since 2007, there has been a concerted effort to increase the awareness and understanding for RAP use in HMA. As of 2009, twenty-one State highway agencies, out of fifty-one, increased the amount of RAP permitted and twenty-three State highway agencies now have experience with high RAP mixes (Jones 2009). While many State highway agencies increased the amount of RAP used in HMA, high amounts of RAP (i.e. greater than 25%) are still not common in State projects. Many State DOTs permit more than 25% RAP in HMA layers; however less than half of the States actually use more than 20% RAP in HMA layers. Through current and future efforts of the RAP
