Asphalt Binder Extraction Protocol for Determining Amount

PDF POLICY AND PROCEDURE DIRECTIVE - Home | ADOT

3.5 When more than 15% RAP binder is used, by weight of the total binder in the mix, the RAP binder must be extracted, recovered, and tested during the mix design process. Depending on the results of these tests, the grade of binder supplied to the project may need to be different than the grade specified in the bid documents.

Four tips for controlling asphalt mix designs in the lab

One advantage of determining Gsb-rap this way is that it is still easy to determine the Gmm and asphalt binder content of the RAP to calculate the Gse (RAP). A disadvantage to this method is that the accuracy is highly dependent on how well the percentage of absorbed asphalt could be estimated.

PDF Managing Reclaimed Asphalt - Adept

Asphalt is a manufactured product containing only aggregate and binder with some other minor components. It is not necessary to determine the bitumen content directly because anything not tar can be assumed to be bitumen. If necessary the binder content can be determined using one of the physical methods in BS EN 12697-1.
