A method for making asphalt concrete comprising: providing a mixer (30; 130; 200) that is adapted to mix aggregate materials and asphalt cement; introducing aggregate materials into the mixer (30; 130; 200); heating the aggregate materials; providing a source of liquid asphalt cement; providing a source of water; providing a foamed asphalt cement nozzle assembly comprising: a foamed cement mixing chamber; a first inlet for liquid asphalt cement; a second inlet for water; an outlet for foamed asphalt cement; introducing the liquid asphalt cement to the foamed cement mixing chamber at an AC rate and introducing the water to the foamed cement mixing chamber at an H 2 O rate to produce foamed asphalt cement; introducing foamed asphalt cement from the outlet of the nozzle assembly into the mixer (30; 130; 200); mixing the foamed asphalt cement with aggregate materials to produce asphalt concrete; characterized by:- at step (c), heating the aggregate materials to a temperature at least as high as the boiling point of water but no higher than about 141°C (285°F); at step, providing the source of liquid asphalt cement at a temperature within the range of about 138°C (280°F) to about 177°C (350°F); at step, said first inlet being in fluid communication with the liquid asphalt cement source and the foamed cement mixing chamber; said second inlet being in fluid communication with the water source and foamed cement mixing chamber; said outlet being in fluid communication with both the foamed cement mixing chamber and the mixer (30; 130; 200); at step: providing an asphalt cement manifold to convey liquid asphalt cement from the source of liquid asphalt cement to the foamed asphalt cement nozzle assembly; providing heating means configured and arranged to transfer heat to the liquid asphalt cement in the asphalt cement manifold; introducing the heated liquid asphalt cement from the asphalt cement manifold to the foamed cement mixing chamber at the AC rate; introducing the water to the foamed cement mixing chamber at the H 2 O rate which is about 0.6-2.0% by volume of the AC rate; wherein the AC rate and the H 2 O rate are selected so that foamed asphalt cement is produced in the foamed cement mixing chamber; at step, mixing the foamed asphalt cement with aggregate materials at a temperature at least as high as the boiling point of water but no higher than about 141°C (285°F). providing a mixer (30;
