Extend the life of existing paved surfaces by repairing aged, cracked, pot holed, and damaged areas.Dan Swayze & Son, Inc. now offers Infrared Asphalt Repair as well as the standard Cut and Patch.
About Infrared
Infrared repair creates a seamless patch by reheating and combining the damaged asphalt with new asphalt mix.Infrared uses "invisible" heat to recycle the existing asphalt.The equipment produces intense infrared wavelengths that reach temperatures exceeding 2000° Fahrenheit.These infrared waves penetrate the surface of the existing asphalt and heat it to a depth necessary for the surface preparation and repair of the damaged area.Asphalt rejuvenator containing light oils lost from the existing asphalt due to time, weather and wear, is added to the prepared area.Fresh hot mix asphalt is added and the area is brought up to the grade, leveled and compacted.This process produces a seamless repair with heat-welded edges.These fused seams don't allow water to penetration like the traditional cut and patch repairs sometimes can.Because Infrared repair is less susceptible to water penetration, it is particularly effective when it can be used in the swales that conduct water to catch basins in large parking lots, apartment complexes or other commercial properties.
Before

Applications for Infrared Usage:
Potholes
Surface cracking of pavement
Leveling trip hazards – ADA areas
Utility cut rehabilitation
Oil stained pavement rehabilitation
Bumps and high spots
Expansion joints
Rough surfaces
Leveling seams in parking lots and roadways
Building up road shoulders and drain gutters
Birdbaths (depressions in pavement that collect water)
Installing speed bumps
Catch basin repair
Reworking curbs
Reshaping asphalt: redirect flow of water/prevent unwanted runoffs
Reshaping asphalt: reshaping areas around drains
Manhole covers: shape asphalt so snowplows don't hit lips
Make a clean joint where asphalt meets concrete
Repair with Infrared
Pothole patches and utility cut repairs often leave small cracks between the new and old pavement.Traffic over road surface depressions and humps create small cracks also.Water can seep through the surface to the base through these very narrow cracks.Roads deteriorate much faster when water has penetrated their surface.
Repair is accomplished in six easy steps:
Sweep away any loose soil or standing water from the area to be repaired.
Position infrared panel over area to be repaired and allow heat to penetrate 5-9 minutes depending on depth, season, and aggregate.
Rake 6" inside heated material removing old joints, seams and rough areas.
Add material if necessary to bring patch to grade and lute to level.
Asphalt Reclaimer - A thermostatically controlled storage unit is used to maintain plant mix asphalt at 300 degrees Fahrenheit for up to 48 hours.This unit facilitates year round patching with permanent material.
Applying this hot-mix with an infrared panel creates a "hot to hot joint".The bonded materials eliminate cracks, and therefore the possibility of water seeping through the surface. In a "cold to hot joint" there is no bond so the surfaces expand and contract at different rates causing cracks.The "hot to hot joint" expands and contracts at the same rate, thus joints will not fail.
The Benefits
Faster repairs – minimal disruption to traffic
No Cold joints – prevents water from entering the pavement through seams, preventing future potholes
Environmentally friendly – less new asphalt required to fill potholes
Cost - the savings realized in materials, manpower and machinery make infrared repairs less expensive than conventional repairs

Cut and Patch Repair
Cut and Patch repair is the standard for treating areas where damage to the asphalt has resulted in a hole that has penetrated to the limestone base. This type of damage cannot be treated by infrared because the base is in poor condition, the existing asphalt is of insufficient thickness or because the asphalt has simply reached its life expectancy. Base material is inspected and corrected as needed. The area is then patched with new asphalt, tamped and smoothed, restoring the damaged area to prime condition.
Crackfilling
Cracks are usually caused by either a failure of the base, water damage or excessive weight on the pavement surface. Cracks can easily be repaired by installing a hot pour material to fill them. The crack sealer provides a waterproof bond and is rubberized to give support while the pavement expands and contracts in changing temperatures. Cracks that go unsealed will continue to allow water into the base structure, causing severe damage to the pavement as the base deteriorates. A pavement crack inspection and correction should take annually.
