Reclaimed Asphalt Pavement (RAP)

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. (1) A second method (hot in-place recycling) involves a ...

While the state of Illinois has been recycling Reclaimed Asphalt Pavement (RAP) material into hot-mix asphalt (HMA) since 1980, there continues to be questions regarding the correct approach to design HMA with RAP. The Illinois Department of Transportation's current method of RAP HMA design provides 100% contribution for the residual asphalt binder from the RAP based on solvent extractions.

Environmental Impacts of Reclaimed Asphalt Pavement (RAP)

The primary goal of this study was to investigate the environmental impacts of reclaimed asphalt pavement (RAP) while it is freshly processed (i.e., fresh HMA) and after subjecting it to accelerated weathering. Three RAP materials were obtained from 3 plants throughout New Jersey; denoted as NORTHRAP, CENTRALRAP, and SOUTHRAP. In addition, a NJ supplier provided fresh HMA loose

An Overview of The RAP Usage Worldwide The percentage of re-used RAP has grown gradually in many countries around the world [3]. Currently, a considerable quantity of this recycled material is used for the production of Hot Mix Asphalt (HMA) and Warm Mix Asphalt (WMA) mixes, which represent the ideal re-use of RAP aggregates as previously mentioned. Nowadays, according to several studies, a ...
