Infrared Asphalt Recycling

Infrared, meaning below red is an invisible wavelength that carries heat. Radiation is a method of heat transfer that allows heat to travel without a physical conduction source. That means that heat can travel through space by invisible wavelength and create energy in the objects that it comes in contact with.

 

Infrared asphalt recycling equipment uses "invisible heat" to recycle asphalt in place. The equipment produces intense infrared wavelengths that reach temperatures exceeding 1200 degrees Fahrenheit and directs them onto the bituminous surface which absorbs the wavelength and creates energy in the asphalt. The energy is heat and this heat conducts through the asphalt to the depth necessary for the scarification and repair to the damaged area. Asphaltic concrete cement absorbs 97% of the infrared energy it is exposed to and turns it into heat. The rate of absorption of the infrared rays will vary depending on the darkness of the surface of the asphalt pavement. Newer, darker pavement will absorb more energy and conduct heat faster than bleached-out oxidized pavement.
