The recycling of asphalt pavement can save a lot of raw materials such as asphalt, sand and gravel, and is conducive to the treatment of waste materials and the protection of the environment.

冷拌瀝青就是冷拌瀝青混合料，是一種瀝青混合料的成型方法，與溫拌瀝青混合料和熱拌瀝青混合料相對應(yīng)。冷拌瀝青混合料的生產(chǎn)是在常溫下，用一定級配的碎石加入乳化瀝青以及添加劑進行拌和而成的瀝青混合料。其與熱拌瀝青混合料相比較，成本低，但是混合料質(zhì)量遠(yuǎn)遠(yuǎn)達(dá)不到熱拌瀝青混合料的質(zhì)量。溫拌理清混合料，這個近期幾年研究得比較多，其質(zhì)量比較好，生產(chǎn)成本跟熱拌的差不多，但是能耗少，施工環(huán)境較好，等。瀝青路面的再生技術(shù)，是將舊瀝青路面經(jīng)過翻挖、回收、破碎、篩分后，與再生劑、新瀝青材料、新集料等按一定比例重新拌和混合料，使之能夠滿足一定的路用性能并用其重新鋪筑路面的一套工藝技術(shù)。

Cold mix asphalt is cold mix asphalt mixture, which is a forming method of asphalt mixture, corresponding to warm mix asphalt mixture and hot mix asphalt mixture. The production of cold mixed asphalt mixture is an asphalt mixture mixed with graded crushed stone and emulsified asphalt and additives at room temperature. Compared with hot mix asphalt mixture, its cost is low, but the quality of mixture is far from that of hot mix asphalt mixture. In recent years, there has been a lot of research on warm mixing and clear mixture. Its quality is relatively good, and the production cost is about the same as that of hot mixing, but the energy consumption is less, and the construction environment is better, etc. The recycling technology of asphalt pavement is a set of technology that mixes the old asphalt pavement with regenerants, new asphalt materials and new aggregates in a certain proportion after digging, recycling, crushing and screening, so that it can meet certain road performance and pave the pavement again.

冷再生機是采用冷再生瀝青混合料的一種再次利用的施工方法，與熱再生相對應(yīng)。冷再生法是用大功率路面銑刨拌和機將路面混合料在原路面上就地銑刨、翻挖、破碎，再加入穩(wěn)定劑、水泥、水（或加入乳化瀝青）和骨料同時就地拌和，用路拌機原地拌和，然后碾壓成型。與熱再生相比，要比熱再生便宜，但是其再生效果較熱再生差，因此大多用在低等級路面的翻修。

Cold recycling machine is a construction method of reusing cold recycled asphalt mixture, which corresponds to hot recycling. The cold recycling method is to mill, dig and crush the pavement mixture on the original pavement with a high-power pavement milling mixer, then add stabilizer, cement, water (or emulsified asphalt) and aggregate, mix in place at the same time, mix in place with a road mixer, and then roll it into shape. Compared with thermal regeneration, it is cheaper than thermal regeneration, but its regeneration effect is worse than thermal regeneration, so it is mostly used in the renovation of low-grade roads.
