Technical characteristics of cold regeneration?
Compared with the traditional road maintenance and reconstruction methods, the road in place cold regeneration process has many incomparable advantages.
1. Low cost
According to the introduction of foreign construction data, compared with the method of paving new materials on the old pavement, the cost of cold recycling in place can be reduced by about 20%~46%.
2. Improve the grade of the old road
The road grade can be improved fundamentally by improving the bearing capacity of the base course, which is of special significance for low-grade highways.
3. Structural integrity
There is no weak interface between thin layers in the uniform thick layer produced by cold recycling construction, which sometimes occurs in traditional construction methods.
4. No damage to subgrade
As the cold recycling construction is a one-time operation, the recycling unit only passes through the exposed subgrade once. Therefore, compared with the traditional construction method, the damage to the subgrade is small.
5. Material saving
All the old paving materials are used locally, which greatly reduces the consumption of new materials and protects resources.
6. Short construction period
As there is no problem of old material transportation, no need for other machinery to loosen and crush the old materials, no need for removal and special crushing of large materials, and more importantly, the one-time operation feature of the construction process greatly simplifies the construction procedure, thus saving construction time.
7. Protect the environment
Because the utilization of old materials greatly reduces the exploitation of new materials, there is no problem of transportation and stacking of old materials. It fundamentally meets the requirements of environmental protection.
