AsphaltPro Magazine | Express Your RAP, RAS Content

Therefore, your mix design should start out with a trial asphalt content of no less than 5.5 percent. For an example, using RAP, let's say the spec allows a maximum RAP binder ratio of 0.25, the RAP has an asphalt content of 4.6 percent, and we would like to design a mix with 30 percent RAP by weight of mix.
