Advantages of Hot Asphalt Recycling Technology
(1) Simple Structure
Hot asphalt recycling is very simple to operate, especially for in-situ hot recycling. All construction equipment forms a complete construction line, so the construction process is relatively simple.
(2) Minimal Impact on Highway Operation
During hot asphalt recycling, only one road can be constructed at a time. Therefore, it is not necessary to close the entire road; only the road under construction needs to be closed, so normal traffic will not be greatly affected. Furthermore, after the asphalt pavement is laid, traffic can be restored in a short time, repairing damaged pavement without affecting normal traffic, effectively reducing losses.
(3) Time Saving
Time saving mainly refers to in-situ geothermal recycling. For plant-mixed hot recycling, the process is relatively complex, and damaged asphalt concrete needs to be transported back to the factory for processing, so its cycle is relatively long. For in-situ geothermal recycling, the entire construction process is completed on-site, and the road can be put into use immediately after construction. Therefore, hot asphalt recycling can effectively save time, allowing damaged road sections to be repaired and put into operation in a short time. (4) Cost Savings
Asphalt thermal recycling technology involves heating and melting damaged asphalt concrete for recycling, thus making rational use of resources and effectively reducing costs in road maintenance, saving resources. Furthermore, on-site geothermal recycling reduces material transportation costs.
(5) Minimal Environmental Impact
If asphalt is discarded into the natural environment, it will cause enormous pollution. In traditional asphalt pavement maintenance, asphalt concrete cannot be recycled and can only be discarded, resulting in a significant environmental impact. Asphalt thermal recycling technology can effectively avoid this problem.
