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

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。冷拌瀝青混合料的生產是在常溫下，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，但是混合料質量遠遠達不到熱拌瀝青混合料的質量。溫拌理清混合料，這個近期幾年研究得比較多，其質量比較好，生產成本跟熱拌的差不多，但是能耗少，施工環境較好，等。瀝青路面的再生技術，是將舊瀝青路面經過翻挖、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。

Cold mix asphalt is a kind of cold mix asphalt mixture, which is a molding method of asphalt mixture, corresponding to warm mix asphalt mixture and hot mix asphalt mixture. The production of cold mix asphalt mixture is a kind of asphalt mixture which is made by adding emulsified asphalt and additives to a certain gradation of crushed stone under normal temperature. Compared with the hot mix asphalt mixture, the cost is low, but the quality of the mixture is far less than that of the hot mix asphalt mixture. In recent years, warm mix has been studied a lot. Its quality is better, its production cost is similar to that of hot mix, but it has less energy consumption, better construction environment, etc. The recycling technology of asphalt pavement is a set of technology that mixes the old asphalt pavement with recycling agent, new asphalt material and new aggregate according to a certain proportion after digging, recycling, crushing and screening, so as to meet certain road performance and use it to re pave the pavement.
              

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。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, corresponding to hot recycling. Cold recycling method is to mill, dig and crush the pavement mixture on the original pavement with high-power milling and mixing machine, then add stabilizer, cement, water (or emulsified asphalt) and aggregate to mix on the spot at the same time, mix in situ with road mixer, and then roll to 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 pavement.
