In fact, compared with the full depth in-situ cold regeneration, the construction depth of the full depth in-situ cold regeneration is about 30-50 cm, and the shallow in-situ cold regeneration is only for the asphalt layer of about 10 cm, which is the direct difference between the two kinds of in-situ cold regeneration.
First, 100% use of old pavement materials.
Second, the construction speed is fast and the construction period is short.
Third, the total investment is small to solve the construction cost.
Fourth, because the asphalt temperature is low, energy conservation and environmental protection are realized.
Explain in detail the on-site cold regeneration technology of cold regeneration and how to construct the on-site cold regeneration of asphalt layer (shallow layer)
From the point of view of global equipment providers, it is mainly the regenerative equipment of Tektronix Inc of the ASTEC group of the United States, and the local regeneration equipment of Wittgen company of Germany. The same points between them are to add cement and other materials in the construction process. The difference between them is that Lu Tek equipment makes the emulsified asphalt to be regenerated, and the equipment of Wittgen company uses foam asphalt to regenerate.
First, let's take a look at the equipment construction of lutec:
A lutec recycling equipment, emulsified asphalt tanker, picker, paver and roller are required.
Before construction, cement shall be distributed on the original pavement by powder spreader. The recycled milling equipment will mill the pavement and add asphalt to the milling room. After mixing in the milling room, it will be transported to the rear, paved by the picker and paver, and finally compacted.
