在“十個(gè)全覆蓋”工程鄉(xiāng)村公路建設(shè)工作中，鄂托克前旗率先采用冷再生技術(shù)工藝，降低建設(shè)成本，減少環(huán)境污染，加快建設(shè)進(jìn)度，取得良好效果。

　　In the construction of rural roads under the "Ten Full Coverage" project, Etuoke Front Banner took the lead in adopting cold recycling technology, reducing construction costs, minimizing environmental pollution, accelerating construction progress, and achieving good results.

　　近日，在鄂托克前旗上海廟鎮(zhèn)哈沙圖嘎查新鋪的鄉(xiāng)村公路施工現(xiàn)場(chǎng)，幾臺(tái)修路機(jī)械排成一列，勻速前行：先由冷再生機(jī)對(duì)地面進(jìn)行銑刨、攪拌，平地機(jī)和輪胎壓路機(jī)緊隨其后，整平突出過后，路面基層基本鋪好。施工現(xiàn)場(chǎng)并沒有大量工人手工作業(yè)，也沒有產(chǎn)生多少廢棄物，短短2個(gè)小時(shí)內(nèi)， 1公里多的新路面已鋪修完畢。同樣的路面，按照傳統(tǒng)工藝，2個(gè)小時(shí)內(nèi)只能修到三四百米。

　　Recently, at the construction site of the rural road in Hashatugacha Xinpu, Shanghai Temple Town, Etuoke Front Banner, several road repair machines were lined up and moving at a constant speed: first, a cold recycling machine milled and mixed the ground, followed by a grader and a tire roller. After leveling and rolling, the road base was basically laid. The construction site did not have a large number of manual workers and did not generate much waste. Within just 2 hours, more than 1 kilometer of new road surface had been paved. According to traditional techniques, the same road surface can only be repaired to three to four hundred meters within two hours.

　　鄂托克前旗“十個(gè)全覆蓋”農(nóng)村公路建設(shè)項(xiàng)目于今年3月15日開工。其中，上海廟鎮(zhèn)建設(shè)總長(zhǎng)為186公里的4級(jí)公路，路面結(jié)構(gòu)層為瀝青混凝土路面，路面寬4.5米。在該項(xiàng)目施工中，施工單位東方路橋集團(tuán)首次引進(jìn)采用了公路冷再生工藝，這項(xiàng)技術(shù)的主要特點(diǎn)是充分利用現(xiàn)有瀝青道路的面層與基層舊鋪層材料，必要時(shí)加入部分新骨料，按比例加入一定量的水泥、泡沫瀝青、乳化瀝青、石灰、粉煤灰等添加劑，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，從而修筑出新基層。

　　The "Ten Full Coverage" Rural Road Construction Project in Etuoke Front Banner started construction on March 15th this year. Among them, Shanghai Miaozhen is constructing a Class 4 highway with a total length of 186 kilometers, and the pavement structure layer is asphalt concrete pavement with a width of 4.5 meters. In the construction of this project, the construction company Dongfang Road and Bridge Group introduced and adopted the road cold recycling process for the first time. The main feature of this technology is to make full use of the old paving materials of the existing asphalt road surface course and base course, add some new aggregates when necessary, add a certain amount of cement, foam asphalt, emulsified asphalt, lime, fly ash and other additives in proportion, and continuously complete the milling, crushing, mixing, paving and compaction of the materials on the spot under the natural environment temperature, so as to build a new base course.

　　與傳統(tǒng)施工方法相比，冷再生技術(shù)具有諸多優(yōu)點(diǎn)：一是成本低，由于全部利用了舊的鋪層材料，減少了道路維修或改造時(shí)舊鋪層材料的挖起運(yùn)輸、廢置和新材料的購置，約可以降低成本20%—46%；二是效率高，冷再生機(jī)械施工可以一次性完成銑刨、破碎、添加、拌和及攤鋪，每天施工可完成5000至8000平方米的工作量，從而簡(jiǎn)化了施工程序，縮短了施工工期；三是質(zhì)量好，冷再生工藝可以根據(jù)不同道路舊鋪層材料的實(shí)際進(jìn)行設(shè)計(jì)，選擇不同的添加劑，形成施工成型厚而均勻的粘結(jié)層，保證了維修后道路的使用期限；四是污染少，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，大量新材料的開采，也會(huì)破壞環(huán)境。采用冷再生技術(shù)則可有效避免上述問題。

　　Compared with traditional construction methods, cold recycling technology has many advantages: firstly, it has low cost. Due to the full utilization of old paving materials, it reduces the excavation, transportation, disposal, and purchase of new materials for road maintenance or renovation, which can reduce costs by about 20% to 46%; Secondly, it has high efficiency. Cold recycling machinery construction can complete milling, crushing, adding, mixing, and paving in one go, and can complete a workload of 5000 to 8000 square meters per day, simplifying the construction process and shortening the construction period; Thirdly, the quality is good. The cold recycling process can be designed according to the actual conditions of different old pavement materials on roads, selecting different additives to form a thick and uniform bonding layer during construction, ensuring the service life of the repaired road; Fourthly, there is less pollution. By using traditional road maintenance methods, the amount of asphalt pavement waste is enormous, causing pollution to the environment. The large-scale mining of new materials also damages the environment. The use of cold regeneration technology can effectively avoid the above-mentioned problems.

　　鄂托克前旗公路段副段長(zhǎng)賀希格吉雅表示，積出色引進(jìn)新的施工技術(shù)，可在確保工程質(zhì)量的基礎(chǔ)上，大幅提高施工進(jìn)度。下一步，鄂托克前旗將進(jìn)一步加大新技術(shù)的推廣力度，確保在規(guī)定時(shí)間內(nèi)完成建設(shè)任務(wù)，力爭(zhēng)提前完成建設(shè)早日通車。

　　He Xigjia, deputy section chief of the Etuoke Front Banner Highway, stated that actively introducing new construction technologies can significantly improve construction progress while ensuring project quality. Next, Etuoke Front Banner will further increase the promotion of new technologies, ensure the completion of construction tasks within the prescribed time, and strive to complete the construction ahead of schedule and open to traffic as soon as possible.

　　截至目前，鄂托克前旗在鄉(xiāng)村公路施工過程中，利用冷再生技術(shù)已完成工程量6萬多平方米。全部工程將在6月30日前全部完工。

　　As of now, more than 60000 square meters of rural road construction have been completed in Etuoke Front Banner using cold recycling technology. All projects will be completed before June 30th.
