冷再生機(jī)租賃簡介

Introduction to Cold Recycling Machine Rental

　　道路冷再生機(jī)租賃是在常溫下使用冷再生機(jī)械（以路星LZS2400型就地冷再生機(jī)為例）連續(xù)完成銑刨和破碎舊路面結(jié)構(gòu)層(包括面層和部分基層)、添加再生材料、拌和、攤鋪等作業(yè)過程，碾壓成型后的攤鋪層可作為低等級(jí)公路的基層或面層及高等級(jí)公路的底基層或基層，屬于道路養(yǎng)護(hù)維修范疇。它主要解決瀝青路面上基層破損的問題。具體講，道路冷再生是指充分利用現(xiàn)有瀝青道路舊鋪層材料（面層與基層）必要時(shí)加入部分新骨料，并按比例加入一 定量的添加劑（水泥、石灰、粉煤灰等）在自然環(huán)境溫度下就地連續(xù)地完成材料的銑刨、破碎、拌和、攤鋪及壓實(shí)成型，從而修筑出具有所需性能質(zhì)量的新基層的作業(yè)過程。

Road cold recycling machine rental refers to the use of cold recycling machinery (taking the Luxing LZS2400 on-site cold recycling machine as an example) at room temperature to continuously complete the milling and crushing of old pavement structural layers (including surface layers and some base layers), adding recycled materials, mixing, paving and other operations. The rolled paving layer can be used as the base or surface layer of low-grade highways and the subgrade or base layer of high-grade highways, which belongs to the scope of road maintenance and repair. It mainly solves the problem of base damage on asphalt pavement. Specifically, road cold recycling refers to the process of fully utilizing existing asphalt pavement materials (surface layer and base layer), adding some new aggregates when necessary, and adding a certain amount of additives (cement, lime, fly ash, etc.) in proportion to continuously mill, crush, mix, spread, and compact the materials on site at natural ambient temperatures, in order to construct a new base layer with the required performance quality.

　　冷再生機(jī)租賃不僅適用于高等級(jí)公路的維修與改造，也適用于一般道路及鄉(xiāng)間公路的維修與改造。此技術(shù)在歐美等國家已得到了較為普遍的應(yīng)用，并常常作為路面維修的首 選方案，隨我國98年引進(jìn)第 一臺(tái)就地冷再生機(jī)后，近幾年來，就地冷再生技術(shù)在我國受到了業(yè)內(nèi)人士普遍的關(guān)注與認(rèn)同，推廣普及速度很快，例如遼寧、吉林及河北等地區(qū)已經(jīng)應(yīng)用相當(dāng)普遍，并且取得了良好的效果。

Cold recycling machine leasing is not only suitable for the maintenance and renovation of high-grade highways, but also for the maintenance and renovation of general roads and rural roads. This technology has been widely applied in countries such as Europe and America, and is often used as the preferred solution for road maintenance. With the introduction of the first on-site cold recycling machine in China in 1998, in recent years, on-site cold recycling technology has received widespread attention and recognition from industry insiders in China, and its promotion and popularization speed is very fast. For example, it has been widely applied in regions such as Liaoning, Jilin, and Hebei, and has achieved good results.

　　冷再生機(jī)租賃的主要施工機(jī)具為集破碎與拌和為一體的冷再生機(jī)。冷再生機(jī)的核心是裝有大量專用刀頭的銑刨和拌和轉(zhuǎn)子。轉(zhuǎn)子向上旋轉(zhuǎn)銑刨原路面材料，冷再生機(jī)向前行進(jìn)時(shí)，轉(zhuǎn)子轉(zhuǎn)動(dòng)，同時(shí)水通過軟管從再生機(jī)連接的水車中運(yùn)送過來，并在再生機(jī)的拌和倉中噴灑。水的輸送量通過微處理器控制的泵送系統(tǒng)精確控制。銑刨轉(zhuǎn)子將水與銑刨料充分拌和，并達(dá)到需要的含水量，從而達(dá)到混合料的大壓實(shí)度。

The main construction equipment for leasing cold recycling machines is a cold recycling machine that integrates crushing and mixing. The core of a cold recycling machine is a milling and mixing rotor equipped with a large number of specialized cutting heads. The rotor rotates upwards to mill the raw road surface material, and when the cold recycling machine moves forward, the rotor rotates. At the same time, water is transported from the water truck connected to the recycling machine through a hose and sprayed in the mixing bin of the recycling machine. The water delivery volume is precisely controlled by a microprocessor controlled pumping system. The milling rotor thoroughly mixes water with the milling material to achieve the required moisture content, thereby achieving high compaction of the mixture.

　　粉狀穩(wěn)定劑，如水泥,白灰，需按設(shè)計(jì)添加量事先撒布在再生機(jī)前的路面上，再生機(jī)將粉狀穩(wěn)定劑與再生料和水一次性拌和。

Powdered stabilizers, such as cement and white ash, need to be spread on the road surface in front of the recycling machine according to the designed addition amount. The recycling machine will mix the powdered stabilizer with recycled materials and water at once.
