Mixing apparatus and method for blending milled asphalt with rejuvenating fluid

In an asphalt pavement resurfacing machine having a transport structure, a heater mounted to said transport structure for heating an underlying asphalt pavement surface to form a heated surface, a mill mounted to said transport structure follow said heater and grind said heated surface to form a milled material and to prepare said underlying surface to a preset depth, a rejuvenating fluid sprayer for introducing a rejuvenating fluid to said milled material and a mixer for blending said milled material with said rejuvenating fluid, the improvement comprising:

• providing said mill with at least two outlets of predetermined breadth;
• providing a respective height monitor at each of said two outlets for determining the height of milled material being discharged from each outlet;
• providing respective forward facing inlets into said mixer for receiving milled material from each said outlet as said machine is advanced in said travel direction;
• providing a respective rejuvenating fluid sprayer for spraying rejuvenating fluid on said milled material adjacent each said outlet;
• said mixer being a pug mill having a housing with a downwardly facing bottom opening;
• and,
• said mixer having a plurality of paddles extending radially from a pug mill shaft housed within said housing, rotatable with said shaft and oriented to blend said rejuvenating fluid with said milled material and to direct a blended material thus formed toward at least one discharge outlet facing rearwardly relative to a travel direction of said resurfacing machine.
