When mixed with an dense-graded aggregate with fine aggregate fractions, a dense-graded and non-porous cold-mix asphaltic improved product is formulated. The improved product may be employed as a patching/paving material or an asphalt treated base, stays pliable for extended periods of time at an ambient temperature, and again meets the typical required specifications and standards, for stability, flow and voids, when tested as hot-mix asphalt or asphalt treated base. ## Claims ### Claim 1 A method for formulating a cut-back binder product for mixing with an aggregate, to produce a cold-mix asphalt product, the method comprising the steps of: a) heating an asphalt base binder;
