May 15, 2014 · Design procedure of hot in-plant recycled asphalt mixture assumes that the residue aged binder in reclaimed asphalt pavement (RAP) is fully blended with virgin binder. However, recent research shows that the interaction between aged binder and virgin binder may not achieve a total blending status.
Learn MoreAsphalt mixture specimens were collected from two asphalt plants. The mixtures were produced with 60/70 and 80/100 binders via both drum and batch mixing plants. The loose mixtures were sampled and immediately placed in an insulated container just after the hot asphalt mixture …
Learn MoreFeb 02, 2018 · All three mixtures contained 50% RAP and were produced in an asphalt plant in three different ways: hot mix, hot mix with a rejuvenator, and warm mix using a foaming technology. The rejuvenator content was 0.4% by weight of asphalt binder. During the production process, the rejuvenator was first added into the virgin binder.
