There is provided a three vehicle train for the continuous cold in-place recycling of asphalt road surface, the train comprising a first supply vehicle containing both water and asphalt emulsion that is in fluid communication with the remaining vehicles; a second milling vehicle for removing a portion of the topmost layer of the road surface as aggregate and evacuating the aggregate via a system of conveyors to a third vehicle; and a third processing vehicle for screening the aggregate to a proper size, mixing the aggregate with cement, water, and/or asphalt emulsion under computer control into a slurry, and depositing the resulting slurry onto the previously milled asphalt road surface.
A processing vehicle adapted to be towed along a roadway to receive milled road surface from a milling vehicle as aggregate, perform a first screening of said aggregate for oversized aggregate, crushing said oversized aggregate as crushed aggregate, perform a second screening of said crushed aggregate to discard remaining oversized aggregate, combine said aggregate and said crushed aggregate passing through said first and second screenings as combined aggregate, weighing said combined aggregate, mixing said combined aggregate with a measured amount of water, Portland cement (“cement”), and asphalt emulsion determined from the weight of said combined aggregate as slurry, and distributing said slurry onto said milled road surface said processing vehicle comprising:
