Abstract
A method for preparing a paving material includes heating an aggregate comprising recycled asphalt pavement using an emitter generating electromagnetic radiation having a wavelength of from 2 microns to 1 millimeter. The method utilizes solid phase autoregenerative cohesion to prepare a material suitable for use as an aggregate in a hot mix asphalt pavement installation.
Claims19
A method for preparing an asphalt paving material, comprising:
- providing an aggregate, wherein the aggregate comprises recycled asphalt pavement;
- generating electromagnetic radiation having wavelengths of from about 1 nm to 5 mm by a resistance wire;
- filtering the generated electromagnetic radiation through a birefringent material to produce a transmitted electromagnetic radiation, wherein the transmitted electromagnetic radiation possesses only a subset of the wavelengths of the generated electromagnetic radiation;
- and
- heating the aggregate using only the transmitted electromagnetic radiation, whereby an asphalt paving material is obtained.
