Impact of milling machine parameters on the properties of reclaimed asphalt pavement

When using a high content of reclaimed asphalt pavement (RAP) in production, the RAP properties play primary role defining performance new mixture. The depend not only on composition old but also milling process. Here we performed full-scale experiment at four jobsites. At each them, three machine parameters were varied (moving speed, depth, and drum rotational speed), while everything else remained constant (pavement type, etc.). results demonstrate that increasing moving speed generates larger chunks. There is evidence large chunks more filler. Finally, found temperature picks does age binder aggregate angularity correlate with parameters.
