冷再生機(jī)是一種用于路面養(yǎng)護(hù)和建設(shè)的多功能設(shè)備，主要用于對(duì)舊路面進(jìn)行銑刨、破碎、添加、拌和及攤鋪等作業(yè)，以實(shí)現(xiàn)舊路面的升級(jí)改造或基層、底基層的穩(wěn)定土現(xiàn)場(chǎng)拌和。以下是冷再生機(jī)的主要優(yōu)點(diǎn)和特點(diǎn)：

　　Cold recycling machine is a multifunctional equipment used for road maintenance and construction, mainly used for milling, crushing, adding, mixing, and paving operations on old road surfaces, in order to achieve the upgrading and transformation of old road surfaces or on-site mixing of stable soil for base and sub base layers. The following are the main advantages and features of a cold regeneration machine:

　　成本低：冷再生機(jī)利用舊路面材料，減少了新料的購(gòu)置和舊料的開(kāi)挖、運(yùn)輸、廢置等費(fèi)用，成本降低約20%至46%13。

　　Low cost: The cold recycling machine utilizes old road materials, reducing the purchase of new materials and the costs of excavating, transporting, and disposing of old materials, resulting in a cost reduction of approximately 20% to 46%.

　　提高道路等級(jí)：通過(guò)提高基層承載力，從根本上改善道路質(zhì)量，對(duì)低等級(jí)公路意義重大13。

　　Improving road grade: By increasing the carrying capacity of grassroots, fundamentally improving road quality is of great significance for low-grade highways.

　　結(jié)構(gòu)完整性：冷再生施工產(chǎn)生的鋪層內(nèi)不存在傳統(tǒng)施工方法中較薄鋪層間的薄弱界面13。

　　Structural integrity: There are no weak interfaces between the thinner layers in traditional construction methods within the layers produced by cold recycling construction.

　　不損傷路基：冷再生機(jī)采用一次性作業(yè)方式，對(duì)路基的損傷較小13。

　　Not damaging the roadbed: The cold recycling machine adopts a one-time operation method, which causes less damage to the roadbed.

　　節(jié)省材料：所有舊材料層被利用，大大降低了新材料的用量，保護(hù)了資源13。

　　Save materials: All old material layers are utilized, greatly reducing the amount of new materials and protecting resources.

　　施工周期短：冷再生機(jī)施工可一次性完成多項(xiàng)作業(yè)，簡(jiǎn)化了施工程序，縮短了工期4。

　　Short construction period: Cold recycling machine construction can complete multiple tasks at once, simplifying the construction process and shortening the construction period by 4.

　　受天氣影響小：冷再生機(jī)在天氣條件不確定的情況下也能施工，除大雨外，一般陰晴不定或小雨天氣均可施工，大雨后也可立即恢復(fù)施工4。

　　Less affected by weather: The cold recycling machine can also be used for construction in uncertain weather conditions. Except for heavy rain, it can generally be used for construction in cloudy or sunny weather or light rain. Construction can also be resumed immediately after heavy rain.

　　環(huán)保優(yōu)勢(shì)：冷再生施工工藝節(jié)約資源，減少環(huán)境污染，被稱(chēng)為綠色施工技術(shù)4。

　　Environmental advantages: Cold recycling construction technology saves resources and reduces environmental pollution, known as green construction technology 4.

　　其他特點(diǎn)：冷再生機(jī)具有無(wú)極變速行走驅(qū)動(dòng)、多碟式制動(dòng)器、噪音控制、左右側(cè)移技術(shù)、人性化設(shè)計(jì)、優(yōu)良混合性、強(qiáng)大切向力等特點(diǎn)，部分型號(hào)還具備多種轉(zhuǎn)向方式和功率自分配技術(shù)256。

　　Other features: The cold regeneration machine has features such as stepless variable speed walking drive, multi disc brake, noise control, left and right lateral displacement technology, humanized design, excellent mixing performance, and strong tangential force. Some models also have multiple steering modes and power self distribution technology.

　　綜上所述，冷再生機(jī)在成本、效率、環(huán)保、施工質(zhì)量等方面具有顯著優(yōu)勢(shì)，是現(xiàn)代道路養(yǎng)護(hù)和建設(shè)的重要設(shè)備。

　　In summary, cold recycling machines have significant advantages in cost, efficiency, environmental protection, and construction quality, and are important equipment for modern road maintenance and construction.

　　冷再生機(jī)是一種施工機(jī)械，它的大優(yōu)點(diǎn)就是工作效率高，而且用途極廣。一般都用于瀝青混凝土路面的銑刨以及舊瀝青路面的再生，在很多公路、城鄉(xiāng)道路以及碼頭、停車(chē)場(chǎng)等工程都看到它的身影。由此看來(lái)，它主要用于道路維修維護(hù)以及改造上。與傳統(tǒng)的道路維修方法不同的，它有著很多不同的優(yōu)點(diǎn)。

　　Cold recycling machine is a construction machinery, its major advantage is high work efficiency, and it has a wide range of uses. It is generally used for milling asphalt concrete pavement and regenerating old asphalt pavement, and can be seen in many highways, urban and rural roads, as well as docks, parking lots and other projects. From this perspective, it is mainly used for road maintenance and renovation. Unlike traditional road maintenance methods, it has many different advantages.

　　一是拌合機(jī)操作成本比較低。如果是舊鋪層上加鋪新料，那成本明顯高于直接使用冷再生機(jī)三至四成，目前很多人就選擇了這種施工機(jī)械來(lái)操作，省時(shí)省力，而且省費(fèi)用。二是提高舊路等級(jí)。通過(guò)拌合機(jī)可以提升基層承載力，從另一角度來(lái)看，就是提高了道路等級(jí)，對(duì)于一些低等級(jí)的公路是非常有意義的。三是它可以維護(hù)好施工結(jié)構(gòu)的完整性。因?yàn)檫@種拌合機(jī)施工時(shí)產(chǎn)生的效果非常好，對(duì)于較厚鋪層依然可以保持均勻，不像傳統(tǒng)施工方法經(jīng)常出現(xiàn)的較薄鋪層間的界面。

　　One reason is that the operating cost of the mixer is relatively low. If new materials are added to the old layer, the cost is significantly 30% to 40% higher than using a cold recycling machine directly. Currently, many people choose this type of construction machinery to operate, which saves time, effort, and costs. The second is to upgrade the level of old roads. By using a mixer, the bearing capacity of the base layer can be improved. From another perspective, it increases the road grade, which is very meaningful for some low-grade highways. Thirdly, it can maintain the integrity of the construction structure. Because this type of mixer produces very good results during construction, it can still maintain uniformity for thicker layers, unlike the interface between thinner layers that often occurs in traditional construction methods.

　　此外，鑒于冷再生機(jī)的特點(diǎn)，它一般都是一次性作業(yè)為主，再生機(jī)組對(duì)于暴露在外的路基只通過(guò)一次，所以與傳統(tǒng)的工藝相比，它對(duì)于路基的破壞力是比較小的。而且在節(jié)約材料方面，它也是很小的，所有的舊鋪層材料都可以在次使用，大大減少了新材料的用量，也不存在舊料需要運(yùn)輸及堆放問(wèn)題。

　　In addition, considering the characteristics of cold recycling machines, they are generally operated in one go. The recycling unit only passes through the exposed roadbed once, so compared with traditional processes, its destructive power on the roadbed is relatively small. Moreover, in terms of material conservation, it is also very small. All the old paving materials can be reused, greatly reducing the amount of new materials used and eliminating the need for transportation and stacking of old materials.
