Evaluation of Recycled Base Aggregates

Recycled asphalt pavement (RAP) and recycled concrete aggregate (RCA) are materials processed from existing pavements and used in new pavement construction projects. The environmental and economic benefits of reusing waste materials have made RAP and RCA popular in base course applications in Wisconsin for more than 30 years.

Asphalt concrete - Wikipedia

Asphalt concrete mixes may also contain reclaimed asphalt shingles (RAS). Research has demonstrated that RAP and RAS can replace the need for up to 100% of the virgin aggregate and asphalt binder in a mix, but this percentage is typically lower due to regulatory requirements and performance concerns. In 2019, new asphalt pavement mixtures ...
