施工準備工作是保證冷再生技術順利開展的前提，施工準備期間需要對道路的信息情況進行充分的采集與分析，從而制定出一個合理的施工方案。主要任務有以下幾點：一是對原路面的使用情況和原路面所處的環境進行調查，并對相關的數據進行統計。二是對原路面的嚴重損害路段進行預處理，結合路面的實際情況對中下面層進行徹底修復，確保基礎的承載力。三是合理調配人、材、機，在進行冷再生技術前應該對建設施工過程中所需用到的材料和設備等進行檢查，保證其滿足施工的要求。四是進行鋪設試驗段，既能測量出各環節的施工所需要的溫度以及施工速度等相關數據，又能對各項指標做出檢測，因此鋪設試驗段很有代表性。

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。在施工前進行放樣操作，并打格計量卸放水泥，水泥量按5%計，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）冷再生機銑刨拌合。用冷再生機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。銑刨速度根據舊路結構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行。單幅拌合長度應控制在200m以內。拌和時由再生機電腦控制加水量。

(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.

隨著社會的可持續發展，瀝青混凝土路面冷再生技術的發展越來越成熟，受到人們的關注和喜愛也越來越多，且其優勢也逐漸顯現出來：投資的成本較低；施工所需的時間較短；提高了材料的利用率從而提高了資源的利用率；尤其是傳統的技術運用無機材料，污染性很高，冷再生技術的應用減少了對環境的污染。因此冷再生技術在公路建設方面，給社會帶來了更多的經濟效益，推動了社會的可持續發展。

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.
