為什么需要利用冷再生施工，究竟冷再生機(jī)租賃公司租賃的冷再生設(shè)備能具有多大的作用，它的施工速率如何，成本增加不高，究竟怎么樣，接下來(lái)讓大黃蜂工程機(jī)械給各位解釋關(guān)于冷再生施工的幾個(gè)優(yōu)點(diǎn)。

Why do we need to use cold regeneration for construction? What is the function of the cold regeneration equipment leased by the cold regeneration machine leasing company? What is its construction rate and low cost increase? Next, let Bumblebee engineering machinery explain several advantages of cold regeneration construction to you.

1.低成本：道路就地冷再生機(jī)因?yàn)樗欣昧伺f的路面起模原材料，進(jìn)而降低了道路檢修或更新改造時(shí)舊起模原材料的基坑開(kāi)挖、運(yùn)送、廢置和新型材料的購(gòu)買(mǎi)，進(jìn)而造成成本費(fèi)大幅降低。選用道路就地冷再生比傳統(tǒng)式方法對(duì)比，伴隨著再生層薄厚的不一樣，能夠 控制成本，冷再生路面薄厚越厚，控制成本越多。如05年吉林省線(xiàn)磐石段改建工程的施工，經(jīng)經(jīng)濟(jì)發(fā)展技術(shù)性互斥計(jì)劃方案較為后，選用混凝土冷再生施工加工工藝開(kāi)展道路農(nóng)村基層的再生利用，節(jié)省項(xiàng)目投資近43%。再生薄厚為27cm，再生層工程預(yù)算為42元/m2，而選用傳統(tǒng)手工藝，需雙層水穩(wěn)加固，加上原路面原材料需消除外調(diào)，工程造價(jià)為73元/m2，此后例中由此可見(jiàn)冷再生技術(shù)性可使工程成本大幅度降低。在路面農(nóng)村基層因其原料的再利用可節(jié)約很多項(xiàng)目投資，在低級(jí)別路面中，因用冷再生加工工藝可提升路面農(nóng)村基層級(jí)別而減少整體面層的資金投入，這類(lèi)客觀性具體優(yōu)勢(shì)的存有是促使就地冷再生技術(shù)性遭受認(rèn)可而且獲得迅速發(fā)展趨勢(shì)的原始動(dòng)力。

1. Low cost: the road local cold recycling machine uses all the old road formwork raw materials, which reduces the foundation pit excavation, transportation and waste of the old formwork raw materials and the purchase of new materials during road maintenance or renewal, resulting in a significant reduction in the cost. Compared with the traditional method, the local cold regeneration of the road can control the cost with the difference of the thickness of the regeneration layer. The thicker the thickness of the cold regeneration pavement is, the more the control cost is. For example, in the construction of the reconstruction project of Panshi section of Jilin Provincial Railway in 2005, after the technical mutual exclusion plan of economic development is relatively, the cold recycling construction and processing technology of concrete is selected to carry out the recycling of rural road base, saving nearly 43% of the project investment. The thickness of the recycled layer is 27cm, and the engineering budget of the recycled layer is 42 yuan / m2. However, the traditional handicraft is selected, which needs double-layer water stability reinforcement. In addition, the external transfer of raw materials of the original pavement needs to be eliminated, and the engineering cost is 73 yuan / M2. In the following example, it can be seen that the cold recycling technology can greatly reduce the engineering cost. In the rural base course of pavement, the reuse of its raw materials can save a lot of project investment. In the low-level pavement, the use of cold regeneration processing technology can improve the level of rural base course of pavement and reduce the capital investment of the overall surface course. The existence of such objectivity and specific advantages is the original power to promote the recognition of in-situ cold regeneration technology and obtain the rapid development trend.

2.效率高：道路就地冷再生機(jī)械設(shè)備施工一次性能夠 進(jìn)行瀝青道路、粉碎、加上、攪拌及鋪筑，進(jìn)而簡(jiǎn)單化了施工程序流程，減少施工施工期。應(yīng)用就地冷再生機(jī)械設(shè)備，每日施工可進(jìn)行平米的勞動(dòng)量。

2. High efficiency: the construction of road local cold recycling machinery and equipment can carry out asphalt road, crushing, addition, mixing and paving at one time, which simplifies the construction procedure and reduces the construction period. The local cold regeneration mechanical equipment shall be applied, and the daily construction can carry out the labor volume of square meters.

3.受氣溫標(biāo)準(zhǔn)危害?。号f地冷再生可以在氣溫自然環(huán)境不確定性的標(biāo)準(zhǔn)下施工，除開(kāi)在降水量很大時(shí)，一般的變幻無(wú)常的氣溫，毛毛雨氣溫，冷再生機(jī)均可施工，即便在暴雨之后，也可立刻修復(fù)施工。

3. Little harm by the temperature standard: the old land cold regeneration can be constructed under the standard of temperature and natural environment uncertainty. Except for the general changeable temperature, drizzle temperature and cold regeneration machine when the precipitation is large, the cold regeneration machine can be constructed. Even after the rainstorm, it can be repaired immediately.

4.對(duì)城市公共交通危害明顯降低：冷再生租用施工的特性是冷再生工藝流程簡(jiǎn)潔明了，施工設(shè)備少，對(duì)交通出行影響體現(xiàn)不比較敏感全部冷再生機(jī)械設(shè)備組成能夠 處在同一條行車(chē)道內(nèi)，不危害另一條行車(chē)道機(jī)動(dòng)車(chē)行駛，可開(kāi)展敞開(kāi)式施工，非常適用車(chē)流量很大或路寬窄小狀況下的道路的施工。當(dāng)?shù)缆钒敕┕r(shí)，另半幅仍舊啟用，進(jìn)而大大的改進(jìn)施工情況下的交通條件。因而，做為一種效率高、環(huán)保節(jié)能、環(huán)境保護(hù)道路檢修方式和新技術(shù)新工藝，路面冷再生機(jī)早已變成國(guó)際性上道路更新改造的關(guān)鍵方式之一。

4. The harm to urban public transport is significantly reduced: the characteristics of cold regeneration rental construction are that the cold regeneration process is simple and clear, there are few construction equipment, and it is not sensitive to the impact on traffic travel. All the components of cold regeneration machinery and equipment can be in the same lane without endangering the driving of motor vehicles in another lane, and open construction can be carried out, It is very suitable for the construction of roads with large traffic flow or narrow road width. When half of the road is constructed, the other half is still used, which greatly improves the traffic conditions under construction. Therefore, as a road maintenance method and new technology with high efficiency, environmental protection and energy conservation, environmental protection, pavement cold recycling machine has long become one of the key ways of road renewal and reconstruction in the world.

5.施工性?xún)r(jià)比高：就地冷再生施工能夠 依據(jù)不一樣道路舊起模原材料的具體情況開(kāi)展設(shè)計(jì)方案，挑選不一樣的防腐劑，能夠 確保再生原材料的品格和施工品質(zhì)，產(chǎn)生施工成形厚而勻稱(chēng)的粘接層，進(jìn)而確保了檢修后道路的應(yīng)用限期。如青縣一機(jī)廠及滄州市東外環(huán)、吉林省202線(xiàn)工程項(xiàng)目(摻入混凝土使用量為6%)全部再生道路再生層的七天無(wú)側(cè)限抗拉強(qiáng)度均做到3Mpa之上。一般冷再生層的瀝青混合料選用來(lái)源于原貌路面構(gòu)造的瀝青道路料RAP，其冷再生層的點(diǎn)評(píng)關(guān)鍵根據(jù)其抗壓強(qiáng)度來(lái)操縱，其抗壓強(qiáng)度依路面級(jí)別的不一樣由技術(shù)部來(lái)明確，七天無(wú)側(cè)限抗拉強(qiáng)度應(yīng)達(dá)2MPa之上，但針對(duì)混凝土冷再生而言，混凝土使用量一般不可超出6%。假如再生層中粉料過(guò)少，RAP配合比不科學(xué)(其配合比操縱曲線(xiàn)圖可參考混凝土平穩(wěn)砂礫石配合比曲線(xiàn)圖)，但經(jīng)實(shí)驗(yàn)后摻入一部分規(guī)格型號(hào)料來(lái)調(diào)節(jié)配合比，在確?；炷烈磺姓Ｊ褂昧康那疤釛l件下確保再生層品質(zhì)。

5. High construction cost performance: the local cold recycling construction can carry out the design scheme according to the specific conditions of the old formwork starting raw materials of different roads, and select different preservatives, which can ensure the character and construction quality of the recycled raw materials, produce a thick and symmetrical bonding layer formed in the construction, and then ensure the application period of the road after maintenance. For example, the seven day unconfined tensile strength of the recycled layer of all recycled roads of Qingxian No. 1 Machinery Factory, Cangzhou East Outer Ring Road and Jilin line 202 project (the amount of concrete added is 6%) are above 3Mpa. The asphalt mixture of the general cold recycling layer is the asphalt road material rap from the original pavement structure. The key to the evaluation of the cold recycling layer is to operate according to its compressive strength. The compressive strength is determined by the technology department according to the grade of the pavement. The seven-day unconfined tensile strength should be above 2MPa. However, for the cold recycling of concrete, the amount of concrete generally should not exceed 6%. If there is too little powder in the recycled layer, the rap mix proportion is unscientific (the mix proportion control curve can refer to the concrete stable sand gravel mix proportion curve), but after the experiment, some specifications and models are added to adjust the mix proportion, so as to ensure the quality of the recycled layer on the premise of ensuring all the normal use of concrete.

6.具備環(huán)境保護(hù)優(yōu)點(diǎn)：應(yīng)用傳統(tǒng)式的道路檢修方式，瀝清路面廢料量十分大，對(duì)自然環(huán)境導(dǎo)致環(huán)境污染，很多新型材料的采掘，也會(huì)導(dǎo)致資源降低和自然環(huán)境的毀壞，選用傳統(tǒng)式基坑開(kāi)挖施工加工工藝時(shí)，施工單位及小區(qū)業(yè)主均對(duì)很多的“廢棄物”解決頭疼不己，儲(chǔ)放占有很多場(chǎng)所，并導(dǎo)致二次污染。選用冷再生施工，不需解決此外解決廢料料，可避免所述難題。它不但能夠 節(jié)省很多項(xiàng)目投資，更有益于生態(tài)環(huán)境保護(hù)，因而被大家稱(chēng)作“翠綠色”施工技術(shù)性。

6. It has the advantages of environmental protection: using the traditional road maintenance method, the amount of pavement waste is very large, which leads to environmental pollution to the natural environment. The excavation of many new materials will also lead to the reduction of resources and the destruction of the natural environment. When using the traditional foundation pit excavation construction processing technology, the construction unit and community owners have a headache for many "wastes", Storage occupies many places and leads to secondary pollution. Cold recycling construction is selected, which does not need to be solved. In addition, the problem can be avoided by solving the waste material. It can not only save a lot of project investment, but also be beneficial to ecological and environmental protection. Therefore, it is called "emerald green" construction technology.
