冷再生技術(shù)是在常溫下使用冷再生機械連續(xù)完成銑刨和破碎，包括面層和部分基層在內(nèi)的舊路面結(jié)構(gòu)層、添加再生材料、拌和、攤鋪、碾壓等作業(yè)過程．重新形成具有一定承載能力的結(jié)構(gòu)層的一種工藝。

Cold recycling technology is a process that uses cold recycling machinery to continuously complete milling and crushing at room temperature, including the old pavement structural layer including surface layer and part of base layer, adding recycled materials, mixing, paving, rolling and other operation processes, so as to re form the structural layer with certain bearing capacity.

瀝青路面冷再生技術(shù)大大加強了新罩面或循環(huán)使用等方法，延長了路面的質(zhì)量并延伸道路的使用壽命。

The cold recycling technology of asphalt pavement greatly strengthens the new overlay or recycling methods, extends the quality of the pavement and extends the service life of the road.

瀝青路面冷在生技術(shù)與傳統(tǒng)的瀝青路面維修方式相比，能夠節(jié)約大量的瀝青、砂石等原材料，節(jié)省工程投資，同時有利于廢料處理、保護環(huán)境，因而具有顯著的經(jīng)濟效益和社會效益。隨著人們對環(huán)保、社會效益的關(guān)注及技術(shù)的進步，瀝青路面冷再生技術(shù)越來越受到人們的重視。

Compared with the traditional maintenance methods of asphalt pavement, the cold in life technology of asphalt pavement can save a lot of asphalt, gravel and other raw materials, save engineering investment, and is conducive to waste treatment and environmental protection. Therefore, it has significant economic and social benefits. With people's attention to environmental protection, social benefits and technological progress, the cold recycling technology of asphalt pavement has attracted more and more attention.

國外對瀝青路面再生使用研討，早期是美國從1915年開始的，到上世紀八十年代底美國再生瀝青混合料的用量幾乎為悉數(shù)路用瀝青混合料的一半，并且在再生劑開發(fā)、再生混合料設(shè)計、施工設(shè)備等方面的研討也日趨深化。在美國瀝青路面的再生使用已是常規(guī)實踐。一般來說，使用15%~25%的回收路面資料(RAP)的瀝青混合料性能都很好。

The research on the recycling of asphalt pavement abroad began in the United States in 1915. By the end of 1980s, the amount of recycled asphalt mixture in the United States was almost half of all road asphalt mixtures, and the research on the development of recycling agent, the design of recycled mixture and construction equipment was deepened day by day. The recycling of asphalt pavement is a common practice in the United States. Generally speaking, the performance of asphalt mixture using 15% ~ 25% recycled pavement data (RAP) is very good.
