1. A method for installing hot asphalt pavement, comprising:
- providing an aggregate, wherein the aggregate comprises recycled asphalt pavement;
heating the aggregate to a temperature of from about 350°
F. to about 400°
F. using an emitter, wherein the emitter comprises a birefringent material through which electromagnetic radiation generated by the emitter passes, wherein the emitter generates electromagnetic radiation having a wavelength of from about 1 nm to 5 mm;
adding the aggregate to an asphalt in a mill to yield a mixture of aggregate with baked-on asphalt;
laying the mixture down over a base to form a first layer of lift; and
compacting the first layer, whereby a hot asphalt pavement is installed.

Abstract
A method for installing hot asphalt pavement includes heating an aggregate to a temperature of from about 350° F. to about 400° F. using an emitter comprising a birefringent material, the emitter generating electromagnetic radiation having a wavelength of from 2 microns to 1 millimeter, wherein the aggregate is a recycled asphalt pavement; adding the aggregate to an asphalt in a mill to yield a mixture of aggregate with baked-on asphalt; laying the mixture down over a base to form a first layer of lift; and compacting the first layer.
