The operation is very similar to the hot process, but as the name implies there is not heat. The asphalt pavement material removed from the roadway can be fed into a drum mixer or a conventional batch plant as shown in Figure 6 (Epps, et a 1 , 1980). The reclaimed material is mixed with new aggregates, asphalt and/or modifiers in the plant.


The selected asphalt binder PG for this study was PG 58-28. Asphalt binder was blended with two ReOB products from two different manufacturers (CC-type and SK-type) at various percentages of ReOB (3%, 6%, and 9%). All asphalt binders (six different blends in addition to the control) were characterized using the SuperPave asphalt binder PG system.
