Patent ID: 8734581

Claim:
A bituminous paving process, which process comprises: a) mixing an asphalt binder, aggregate and 0.1-1.0 wt % lubricating additive based on the asphalt binder weight at a first temperature greater than 160° C. to form a bituminous mix consisting essentially of aggregate coated with asphalt binder and lubricating additive, wherein the lubricating additive comprises lubricating non-aqueous surfactants, non-surfactant additives, acids or combinations thereof, and wherein a blend of the asphalt binder and lubricating additive has a measured maximum normal force no more than about 5.5 Newtons at 90° C. using a dynamic shear rheometer with a 50 μm gap, and b) compacting the bituminous mix at a second temperature less than 130° C. and at least about 55° C. below the first temperature to provide bituminous pavement having field density values of less than 10% in place air voids for the compacted bituminous mix.
