In the previous road construction, it was necessary to eradicate the old asphalt pavement, resulting in a lot of waste. Now the emergence of cold regenerator can reduce waste. Cold recycling machine refers to the in-situ cold recycling of asphalt pavement. It uses the integrated recycling equipment, added materials and one-time mixing and forming process to form a new complete system for the reconstruction of old pavement through the newly paved structural surface.
