| 1st Process
(PRE-HEATER) |
[Asphalt Surface Heating]
The aged asphalt surface is preheated using infrared heaters. Heating Depth: 50mm / Working Speed: 1.5~8m/min |
|---|---|
| 2nd Process
(PRE-HEATER) |
[Asphalt Surface Heating]
The surface preheated in the first process is further heated for reaching intermediate temperature. Heating Depth: 50mm / Working Speed: 1.5~8m/min |
| 3rd Process
(RECYCLER) |
[Asphalt Surface Heating]
The preheated surface is additionally heated before the cutting process to maintain intermediate temperature. Heating Depth: 50mm |
| 4th-1 Process
((RECYCLER) |
[Primary Asphalt Cutting]
The heated asphalt surface is scraped using cutting blades. cutting Depth: 25~50mm cutting width : 2.6~3.6m |
| 4th-2 Process
(RECYCLER) |
[Secondary Asphalt Cutting and Collection]
The heated asphalt surface is milled and collected using cutting Depth: 25~50mm cutting width : 2.6~3.6m |
| 5th Process | [Asphalt Recycling] The collected asphalt is scraped and gathered, and then recycling additives are sprayed and mixed. After recycling, it is discharged using a paving machine (conveyor-driven). Asphalt Recycling Capacity: 0.6~3.2 tons/min (based on a working width of 3.6m) |
