Infrared thermal bond, bituminous pavement patching is a method of applying infrared heat, blending new asphalt with the existing asphalt to create a joint-free integral patch. The machine can heat the existing blacktop to a depth of approximately two inches without oxidation or burning. There is no flame in direct contact with the existing blacktop surface.
The unit is also equipped with chambers that are able to store up to four tons of fresh bituminous materials at a consistent temperature.
ADVANTAGES OF INFRARED PATCHING
- Time. Depending on air temperature, the entire process will take approximately 6-15 minutes. The older and more traditional method of rip and replacement requires sawing, excavating, and repaving which can take hours if not days.
- Convenience. The thermal bond patching machine hauls blacktop which it can heat and insulate so work can be performed even when blacktop plants are not operating.
- Quality. Without cold joints created, cracks don’t develop between the old pavement and the repaired area.
Applications of Infrared Patching:
- Utility Cuts
- Bird Baths (Low Spots)
- Heaving (High Spots)
- Pavement Seams
- Alligator | Spiderweb Cracking
- Failed Repairs
