The cold recycled HMA final mixture corresponds to the hot recycled HMA final mixture. The cold recycling method is to use a pavement milling machine to mill, dig, and crush the original pavement on the spot, then add stabilizers, cement, water (or add emulsified asphalt) and aggregates to mix on the spot, and finally roll the shape. Compared with hot recycling construction, cold recycling construction is cheaper, and its recycling effect is worse than hot recycling, so it is mostly used in the renovation of low-grade roads. Hot recycled HMA final mixture are mostly used for high-grade pavements.
