INFRARED THERMAL BOND PATCHING
Infrared thermal bond bituminous pavement patching is a method of blending new blacktop with infrared-heated existing blacktop to create a joint-free integral patch. The machine is capable of heating 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.
The Process:
- Layout anf mark area to be repaired.
- Lower infrared-heating unit over the pothole.
- Etch the outer edge of the heated patch area and rake the old blacktop.
- Add fresh 300ºF blacktop before final raking.
- Roll and compact the blacktop with a vibratory roller.
- Patch completed in approximately 15 minutes.
