Why use infrared repair methods?
The application of an asphalt-recycling program is to repair potholes, sunken utility cuts, depressions/poor water drainage, high spots, cracks, alligator areas, catch basins, oil spots and pavement decoration. The program is intended for repair of existing localized pavement distresses not caused by inadequate pavement thickness, weak sub grade, and poor quality of materials in adjacent areas and/or improper drainage of the pavement components.
Infrared asphalt recyclers are a cost-effective method of asphalt repair. Infrared repair techniques are faster than cutting out and replacing asphalt and they do not leave a joint around the perimeter of a repair for water to seep into. Infrared asphalt recyclers warm the existing asphalt in and around the repair area to over 300 degrees Fahrenheit - the same temperature that new asphalt is when manufactured at the plant. The softened asphalt can be scarified to mix in hot liquid binder and fresh asphalt, if needed, before compaction. This results in a permanent and attractive repair that has recycled the existed asphalt.
Typical Repairs:
1. Potholes
2. Sunken utility cuts
3. Depressions/poor water drainage
4. High spots
5. Cracks
6. Catch basins
7. Oil spots
8. Pavement decoration
Recycling: Why waste perfectly good asphalt?
Permanent Repair: Seamless welded edges. No joint for water to seep through.
Cost Efficient: Infrared repairs are less expensive to complete than conventional repairs, because there is
little new asphalt required and no unnecessary equipment involved.
Time Savings: Eliminate saw cutting, jack hammering, removal, loading, and
trucking. No holes left in parking area waiting for mishaps. Pavement repairs can be
made in 25% of the time it takes to do a conventional remove and replace repair.
What is infrared heat?
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. Discovered in 1800, infrared radiation can be defined as invisible heat that can travel through space creating energy in the objects that it comes in contact
with.
Infrared asphalt recycling equipment uses "invisible heat" to emplace recycled asphalt. The equipment produces intense infrared wavelengths that reach temperatures near 1200 degrees Fahrenheit and directs them onto the bituminous surface that 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 of the damaged asphalted area.
Asphalt Concrete absorbs up to 97% of the INFRARED energy it is exposed to and turns it into heat. Of course this will vary depending on the darkness of the surface. Newer, darker pavement will absorb more energy and generate heat faster than old oxidised pavement.
