| description | A foamed asphalt cement nozzle assembly is adapted for use in connection with a mixer for mixing aggregate materials and asphalt cement to make asphalt concrete. The foamed asphalt cement nozzle assembly includes a foamed cement mixing chamber, a first inlet for liquid asphalt cement and a second inlet for water, each of which is in fluid communication with the foamed cement mixing chamber. An outlet for foamed asphalt cement is also provided, which outlet is in fluid communication with both the foamed cement mixing chamber and the mixer. The invention also comprises a method for making asphalt concrete using foamed asphalt cement. The method includes introducing aggregate materials into the mixer and heating the aggregate materials to a temperature at least as high as the boiling point of water but no higher than about 285° F. The method also includes introducing liquid asphalt cement and the water to the foamed cement mixing chamber so as to produce foamed asphalt cement, and introducing foamed asphalt cement into the mixer and mixing it with aggregate materials at a temperature at least as high as the boiling point of water but no higher than about 285° F. to produce asphalt concrete. The invention also includes an apparatus for making asphalt concrete which includes a foamed asphalt cement nozzle assembly. |
