Abstract
A method for repairing asphalt pavement involves passing an emitter over a surface of a damaged asphalt pavement comprising aged asphalt, wherein the emitter comprises a birefringent material through which the electromagnetic radiation generated by the emitter passes, wherein the emitter generates electromagnetic radiation having a wavelength of from about 2 microns to 1 millimeter, the radiation penetrating into the pavement to a depth of at least 2 inches, wherein a temperature differential throughout a top two inches of pavement is 100° F. or less, wherein a highest temperature in the top two inches of pavement does not exceed 300° F., and wherein a minimum temperature in the top two inches of pavement is at least 200° F.
