A technique where infrared heating systems apply heat to pavement surfaces and aid in the removal of existing material and replacement with new asphalt mixture. Infrared thermal bond bituminous pavement patching is a method of blending new asphalt mix with infrared heated existing blacktop pavement to create a joint-free integral patch. A special machine is used to 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 which are capable of storing up to four tons of fresh bituminous materials at a consistent temperature.
Infrared Repair Process
- Before repair can be made the area must be heated with infrared machine.
- New mix is added.
- The new mix is heated with the infrared machine.
- The repair is compacted.
- Heating area to be repaired with Infrared machine.
- Adding new mix, heating and compaction.
