The designer must determine the virgin asphalt binder content of the new asphalt mix as part of the volumetric design procedure. During the production of the asphalt mix, the binder present in the RAP and/or RAS will mix with the virgin asphalt binder to produce a final blended binder.

The purpose of requiring a gradation on field samples is to help ensure that the asphalt plant used the same aggregates as reported on the asphalt mix design, in the same proportions. The gradation of all of the aggregates mixed together, plus the design binder content is called the job mix formula (JMF).
The Need for Balance. Today, asphalt mixes are primarily designed under the Superpave system, where proportioning of the aggregates and the asphalt binder relies primarily on empirical aggregate quality characteristics and mix volumetric properties such as air voids, voids in the mineral aggregate (VMA) and voids filled with asphalt (VFA).
Use only FDOT verified mix designs. (Note: For Fine graded Traffic Level D & E mixes, if an FDOT verified design is not available, use a design as approved by the Engineer.) Prior to the production of any Superpave asphalt mixture, submit the proposed mix design with supporting test data indicating compliance with all Superpave mix design criteria.
