Abstract
A method is shown for improving the properties of hot mix asphalt by treating the aggregate which is combined with bituminous binder with lime. A hot quicklime slurry is produced by slaking quicklime with water at the site of the hot mix asphalt plant using a portable mixing tank. The hot quicklime slurry is then applied to the aggregate, the aggregate is dried and combined with the binder to produce the hot mix asphalt.
