A process for recycling the upper surface of an asphaltic surface. The process includes the steps of: (a) rupturing the upper surface to a depth of at least about 1.5 inches to provide a ruptured upper surface overlying the remaining unruptured portion of the asphaltic surface; (b) heating and mixin

A process for recycling the upper surface of an asphaltic surface. The process includes the steps of: (a) rupturing the upper surface to a depth of at least about 1.5 inches to provide a ruptured upper surface overlying the remaining unruptured portion of the asphaltic surface; (b) heating and mixing the ruptured upper surface on the remaining unruptured portion of the asphalt surface to a temperature in the range of from about 100.degree. to about 350.degree. F. to produce a heated, ruptured upper surface which is substantially free of moisture; and (c) pressing the heated, ruptured upper surface to provide a recycled asphaltic surface. An apparatus adapted for carrying out the process is also described.

[ What is claimed is:] [1.] An apparatus moveable along and heating an asphalt surface for recycling said surface comprising:means for rupturing said asphalt surface to a desired depth;at least one pair of adjacent heaters, each heater including at least one heater element, said heaters sequentially applying heat to the ruptured asphalt surface located on the remaining unruptured portion of said asphalt surface to raise the temperature of said ruptured surface to a pre-defined temperature;a mixing means between said pair of heaters to further mix said ruptured surface on the remaining unruptured portion of said asphalt surface after heating by a first heater in said pair and prior to heating by a second heater in said pair; andmeans for pressing said ruptured surface onto said remaining unruptured portion of said asphalt surface after heating and mixing to provide a recycled pavement surface.
