在“十個全覆蓋”工程鄉村公路建設工作中，鄂托克前旗率先采用冷再生技術工藝，降低建設成本，減少環境污染，加快建設進度，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哈沙圖嘎查新鋪的鄉村公路施工現場，幾臺修路機械排成一列，勻速前行：先由冷再生機對地面進行銑刨、攪拌，平地機和輪胎壓路機緊隨其后，整平碾壓過后，路面基層基本鋪好。施工現場并沒有大量工人手工作業，也沒有產生多少廢棄物，短短2個小時內， 1多的新路面已鋪修完畢。同樣的路面，按照傳統工藝，2個小時內只能修到三四百米。

　　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“十個全覆蓋”農村公路建設項目于今年3月15日開工。其中，上海廟鎮建設總長為186的4級公路，路面結構層為瀝青混凝土路面，路面寬4.5米。在該項目施工中，施工單位東方路橋集團引進采用了公路冷再生工藝，這項技術的主要特點是充分利用現有瀝青道路的面層與基層舊鋪層材料，必要時加入部分新骨料，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，在自然環境溫度下，就地連續地完成材料的銑刨、破碎、拌和、攤鋪及壓實成型，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.

　　與傳統施工方法相比，冷再生技術具有諸多優點：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舊鋪層材料的挖起運輸、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50008000的工作量，從而簡化了施工程序，縮短了施工工期；三是質量好，冷再生工藝可以根據不同道路舊鋪層材料的實際進行設計，選擇不同的添加劑，形成施工成型厚而均勻的粘結層，保證了維修后道路的使用期限；四是污染少，使用傳統的道路維修方法，瀝青路面廢棄量十分巨大，對環境造成污染，大量新材料的開采，也會破壞環境。采用冷再生技術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賀希格吉雅表示，積極引進新的施工技術，可在確保工程質量的基礎上，大幅提高施工進度。下一步，鄂托克前旗將進一步加大新技術的推廣力度，確保在規定時間內完成建設任務，力爭提前完成建設早日通車。

　　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.

　　截目前，鄂托克前旗在鄉村公路施工過程中，利用冷再生技術已完成工程量6萬多。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.
