Evaluating Recycling Efficiency of Asphalt Plants Research

this blending efficiency. In other words, some asphalt plants may be able to more efficiently recycle asphaltic materials into mixtures than others, or some asphalt plants may be able to utilize higher recycle percentages than others. At current, the Department has 117 approved plants on …

Recycling long-term-aged asphalts using bio-binder

Aug 30, 2017 · The flow of asphalt is a thermally activated rate process wherein asphalt molecules need to overcome the energy barrier to move to the adjacent site. The activation energy obtained using the viscosity data can be employed to evaluate the resistance of the asphalt molecules to the flow . Fig. 3 shows the related results. The SBS-modified asphalt


The CRM asphalt concrete was produced by adding the crumb rubber into the mix with the baghouse fine return. It then entered the outside compartment of the drum and mixed with the aggregate and was then combined with the asphalt cement. The CRM was transported in a tanker and blown into a silo at Western's plant.
