施工準(zhǔn)備工作是保證冷再生技術(shù)順利開展的前提，施工準(zhǔn)備期間需要對道路的信息情況進(jìn)行充分的采集與分析，從而制定出一個(gè)合理的施工方案。主要任務(wù)有以下幾點(diǎn)：一是對原路面的使用情況和原路面所處的環(huán)境進(jìn)行調(diào)查，并對相關(guān)的數(shù)據(jù)進(jìn)行統(tǒng)計(jì)。二是對原路面的嚴(yán)重?fù)p害路段進(jìn)行預(yù)處理，結(jié)合路面的實(shí)際情況對中下面層進(jìn)行徹底修復(fù)，確保基礎(chǔ)的承載力。三是合理調(diào)配人、材、機(jī)，在進(jìn)行冷再生技術(shù)前應(yīng)該對建設(shè)施工過程中所需用到的材料和設(shè)備等進(jìn)行檢查，保證其滿足施工的要求。四是進(jìn)行鋪設(shè)試驗(yàn)段，既能測量出各環(huán)節(jié)的施工所需要的溫度以及施工速度等相關(guān)數(shù)據(jù)，又能對各項(xiàng)指標(biāo)做出檢測，因此鋪設(shè)試驗(yàn)段很有代表性。

Construction preparation work is a prerequisite for ensuring the smooth implementation of cold recycling technology. During the construction preparation period, it is necessary to fully collect and analyze the information of the road, in order to develop a reasonable construction plan. The main tasks include investigating the usage of the original road surface and the environment in which it is located, and collecting relevant data. The second is to preprocess the severely damaged sections of the original road surface, and thoroughly repair the middle and lower layers based on the actual situation of the road surface to ensure the bearing capacity of the foundation. The third is to reasonably allocate personnel, materials, and machinery. Before implementing cold recycling technology, the materials and equipment required during the construction process should be inspected to ensure that they meet the construction requirements. The fourth is to conduct a laying test section, which can not only measure the temperature and construction speed required for each stage of construction, but also detect various indicators. Therefore, the laying test section is very representative.

（1）清掃路面。在施工準(zhǔn)備工作完成之后一定要徹底打掃路面，清除障礙物，保持路面的整潔，避免路面的雜物給施工的質(zhì)量帶來影響。

(1) Clean the road surface. After the construction preparation work is completed, it is necessary to thoroughly clean the road surface, remove obstacles, maintain the cleanliness of the road surface, and avoid the impact of debris on the quality of construction.

（2）施工放樣，撒布水泥。在施工前進(jìn)行放樣操作，并打格計(jì)量卸放水泥，水泥量按5%計(jì)，確保均勻撒布水泥。

(2) Construction layout, spreading cement. Before construction, carry out layout operations and measure the discharge of cement by grid. The cement amount is calculated at 5% to ensure uniform distribution of cement.

（3）冷再生機(jī)銑刨拌合。用冷再生機(jī)將舊路面和基層銑刨、破碎后混合均勻，噴灑裝置按配比要求噴入乳化瀝青，再將各種材料攪拌均勻。銑刨速度根據(jù)舊路結(jié)構(gòu)狀況和混合料的配合比確定，一般為5-8m/min。瀝青混凝土破碎的最大粒徑不大于30cm。在銑刨、破碎過程中及時(shí)檢測，保證混合料級配符合要求。由于碾壓必須在水泥初凝前進(jìn)行。單幅拌合長度應(yīng)控制在200m以內(nèi)。拌和時(shí)由再生機(jī)電腦控制加水量。

(3) Cold regeneration machine milling and mixing. Use a cold recycling machine to mill and crush the old road surface and base layer, mix them evenly, spray emulsified asphalt into the spraying device according to the ratio requirements, and then mix various materials evenly. The milling speed is determined based on the condition of the old road structure and the mix ratio of the mixture, generally 5-8m/min. The maximum particle size of asphalt concrete crushing shall not exceed 30cm. Timely detection during milling and crushing processes to ensure that the gradation of the mixture meets the requirements. Due to the fact that compaction must be carried out before the initial setting of cement. The length of a single mixing should be controlled within 200m. The amount of water added during mixing is controlled by the regeneration machine computer.

隨著社會(huì)的可持續(xù)發(fā)展，瀝青混凝土路面冷再生技術(shù)的發(fā)展越來越成熟，受到人們的關(guān)注和喜愛也越來越多，且其優(yōu)勢也逐漸顯現(xiàn)出來：投資的成本較低；施工所需的時(shí)間較短；提高了材料的利用率從而提高了資源的利用率；尤其是傳統(tǒng)的技術(shù)運(yùn)用無機(jī)材料，污染性很高，冷再生技術(shù)的應(yīng)用減少了對環(huán)境的污染。因此冷再生技術(shù)在公路建設(shè)方面，給社會(huì)帶來了更多的經(jīng)濟(jì)效益，推動(dòng)了社會(huì)的可持續(xù)發(fā)展。

With the sustainable development of society, the development of cold recycling technology for asphalt concrete pavement is becoming more and more mature, attracting more and more attention and love from people, and its advantages are gradually emerging: lower investment costs; The construction time required is relatively short; Improved material utilization, thereby enhancing resource utilization; Especially with the use of inorganic materials in traditional technologies, the pollution is high, and the application of cold regeneration technology reduces environmental pollution. Therefore, cold recycling technology has brought more economic benefits to society and promoted sustainable development in highway construction.
