就地冷再生技術(shù)與傳統(tǒng)方式的對(duì)比優(yōu)勢(shì)

成本低
Low cost
道路就地冷再生由于全部利用了舊的鋪層材料，從而減少了道路維修或改造時(shí)舊鋪層材料的挖起運(yùn)輸廢置和新材料的購(gòu)置，從而導(dǎo)致成本大幅度下降。采用道路就地冷再生比傳統(tǒng)方式相比，隨著再生層厚度的不同，大概可以降低成本20%—46%，厚度越深，降低成本越多。
On site cold recycling of roads reduces the excavation, transportation, and disposal of old paving materials during road maintenance or renovation, as well as the purchase of new materials, resulting in a significant decrease in costs. Compared with traditional methods, using on-site cold road regeneration can reduce costs by approximately 20% -46% with different thicknesses of the regeneration layer. The deeper the thickness, the more cost can be reduced.
在高等級(jí)路面基層中因原材料的再利用可節(jié)省大量投資，在低等級(jí)路面中，因用冷再生工藝可提高路面基層等級(jí)而減小面層的投入，這種客觀實(shí)際的存在是使得就地冷再生技術(shù)受到認(rèn)同并且得到快速發(fā)展的原始動(dòng)力。
In high-grade pavement base layers, the reuse of raw materials can save a large amount of investment, while in low-grade pavement layers, the use of cold recycling technology can improve the level of pavement base layers and reduce the investment in surface layers. This objective and practical existence is the original driving force for the recognition and rapid development of on-site cold recycling technology.
效率高
efficient
道路就地冷再生機(jī)械施工一次性可以完成銑刨破碎添加拌和及攤鋪，從而簡(jiǎn)化了施工程序，縮短施工工期。使用就地冷再生機(jī)械，每天施工可完成5000——8000平方米的工作量。
The on-site cold recycling machinery construction of roads can complete milling, crushing, mixing, and paving in one go, thereby simplifying the construction process and shortening the construction period. By using on-site cold regeneration machinery, daily construction can complete a workload of 5000-8000 square meters.
此外，冷再生施工的特點(diǎn)是大型機(jī)械，密集施工，將因施工而造成的交通干擾降到了低。不像新建道路施工項(xiàng)目那樣，許多施工可在整個(gè)工地同時(shí)進(jìn)行，冷再生施工只是集中在一定特定的區(qū)域。整個(gè)冷再生機(jī)械組合可以處于同一條車道內(nèi)，不影響另一條車道車輛通行，可進(jìn)行開(kāi)放式施工，非常適用于交通量較大或路寬較窄情況下的道路的施工。
In addition, the characteristic of cold recycling construction is large machinery and intensive construction, which reduces the traffic interference caused by construction to a low level. Unlike new road construction projects, many constructions can be carried out simultaneously throughout the entire construction site, while cold regeneration construction is only concentrated in specific areas. The entire cold recycling machinery combination can be located in the same lane without affecting the traffic of vehicles in the other lane, and can be used for open construction, especially suitable for road construction in situations of high traffic volume or narrow road width.
質(zhì)量好
Good quality
就地冷再生可以根據(jù)不同道路舊鋪層材料的實(shí)際情況進(jìn)行設(shè)計(jì)，選擇不同的添加劑，配比準(zhǔn)確，可以保證再生材料的優(yōu)秀品質(zhì)和施工質(zhì)量，形成施工成型厚而均勻的粘結(jié)層，從而保證了維修后道路的使用期限。如吉林202線工程邯鄲鐵西大街及寶雞太白線（摻加水泥劑量為5%）所有再生路段再生層的7天無(wú)側(cè)限抗壓強(qiáng)度均達(dá)到2.5MPa以上。
In situ cold regeneration can be designed based on the actual situation of different road old paving materials, selecting different additives with accurate proportions, which can ensure the excellent quality and construction quality of the recycled materials, forming a thick and uniform bonding layer for construction, thereby ensuring the service life of the repaired road. For example, the 7-day unconfined compressive strength of the recycled layer in all recycled sections of the Handan Tiexi Street and Baoji Taibai Line (with a cement dosage of 5%) of the Jilin 202 Line project has reached over 2.5MPa.
污染少
Less pollution
使用傳統(tǒng)的道路維修方法，瀝青路面廢棄量十分巨大，對(duì)環(huán)境造成污染，大量新材料的開(kāi)采，也會(huì)造成資源減少和環(huán)境的破壞。采用冷再生技術(shù)則可完全避免上述問(wèn)題。它不僅可以節(jié)約大量投資，更有利于環(huán)境保護(hù)，因此被人們稱之為“綠色”施工技術(shù)。
Using traditional road maintenance methods, the amount of asphalt pavement waste is enormous, causing environmental pollution. The extraction of a large number of new materials can also lead to resource reduction and environmental damage. The use of cold regeneration technology can completely avoid the above problems. It not only saves a lot of investment, but also is more conducive to environmental protection, so it is called a "green" construction technology by people.
冷再生工藝以其傳統(tǒng)工藝無(wú)法比擬的優(yōu)越性，必將會(huì)得到越來(lái)越廣泛的應(yīng)用，一定會(huì)成為道路保養(yǎng)及大修的優(yōu)選工藝。
The cold regeneration process, with its unparalleled advantages compared to traditional processes, will inevitably be increasingly widely used and will become the preferred process for road maintenance and major repairs.
