1. High efficiency
The cold regenerator construction can complete milling, crushing, adding, mixing and paving at one time, simplifying the construction procedure and shortening the construction period.
2. Good construction quality
The design can be carried out according to the actual situation of the old paving materials of different roads. Different additives can be selected and the proportion is accurate, which can ensure the quality of recycled materials and construction quality, and form a thick and uniform bonding layer formed during construction, so as to ensure the service life of the road after maintenance. Generally, the aggregate of the cold recycling layer adopts the milled material rap from the original pavement structure. The evaluation of the cold recycling layer is mainly based on the strength control. The strength is determined by the design department according to the different pavement grades. The 7-day unconfined compressive strength should be more than 2MPa, but for the cold recycling of cement, the cement consumption should not exceed 6%.
3. Low cost
Because the cold recycled layer uses the paving material of the old pavement, it reduces the excavation, transportation, disposal of the old paving material and the purchase of new materials during road maintenance or reconstruction, and reduces the cost. Moreover, the thicker the cold recycled pavement is, the more the cost will be reduced.
4. Little affected by weather conditions
The old land cold regeneration machine can be constructed under the condition of uncertain weather environment. Except in the case of heavy rainfall, the cold regeneration machine can be constructed in general cloudy and sunny weather, light rain weather, and even after heavy rain, the construction can be resumed immediately.
5. Environmental protection advantages
Traditional road maintenance methods will produce a large amount of asphalt waste, which will cause great environmental pollution. The exploitation of new materials will also cause resource reduction and environmental damage. Cold regeneration construction technology can not only save resources, but also be more conducive to environmental protection. Therefore, it is called "green" construction technology.
6. Significantly reduce the impact on public transport
The construction of cold regeneration process is characterized by simple process, few construction facilities and low traffic interference, because the whole set of equipment can be in the same lane, which does not affect the traffic of vehicles in another lane. It can carry out open construction, especially suitable for road construction with large traffic volume or narrow road width. When half of the road is constructed, the other half is opened as usual, which greatly improves the traffic situation. Therefore, as an energy-saving and environmental protection road maintenance method and new technology, the pavement cold recycling machine has become one of the important equipment for road reconstruction.
