Evaluation of the Blending Effectiveness of Reclaimed ...

Dec 12, 2017  There is a recent trend of using a higher content of reclaimed asphalt pavement (RAP) in asphalt pavement construction. When evaluating the properties of mixed RAP and virgin binder and selecting a base binder to be mixed with a high-RAP mix using a blending chart, the effect of partial blending is sometimes neglected and total blending is assumed.
