A New Process and Apparatus for Making Asphalt Concrete

Currf'!nt equipment for making asphalt concrete uses mostly direct-fired processes. In a batch process, the aggregates are directly heated and then mixed with the asphalt cement in a pugmill mixer. In a continuous process, generally known as a drum mix process, the mixture of aggregate and asphalt cement is directly heated. Current systems, particularly drum mix processes, give off and vent to the atmosphere significant amounts of hydrocarbons (blue smoke) and particulate matter. These systems also emit significant amounts of noise, and process problems ace exacerbated by attempts to recycle asphalt concrete.

Asphalt Concrete - an overview ScienceDirect Topics

Asphalt concrete is a combination of two primary ingredients: (i) aggregate and (ii) asphalt cement. Typically, the aggregate constitutes 90–95% (w/w) of the total mixture and the asphalt cement (asphalt binder) constitutes 5–10% (w/w) of the total mixture to form the asphalt concrete.
