冷再生基層施工工藝及質(zhì)量控制

來源：http://kqj188.com/ 日期：2021-06-30 發(fā)布人：

瀝青路面冷再生是利用相結(jié)合的再生設備、添加材料、一次拌和成型工藝，通過新鋪結(jié)構面層，構成舊路面改造新的一套完整體系。再生路面的質(zhì)量與再生工藝、再生材料、再生配合比設計和面層結(jié)構等因素有著直接的關聯(lián)，本文討論的是冷再生基層的施工工藝與質(zhì)量控制的問題。

The cold recycling of asphalt pavement is a new complete system of old pavement reconstruction by using the integrated recycling equipment, adding materials, one-time mixing and forming process, and paving the new structural surface. The quality of recycled pavement is directly related to the factors of recycled technology, recycled materials, recycled mix design and surface structure. This paper discusses the construction technology and quality control of cold recycled base.

1、冷再生基層施工工藝

1. Construction technology of cold recycling base

結(jié)合五一路翻修工程，對冷再生基層施工工藝及其質(zhì)量控制進行探討，為冷再生基層在開封市的推廣應用提供參考經(jīng)驗。工程實踐證明，只要科學組織，嚴格控制，冷再生基層的路用性能更好，而且比常規(guī)維修方法更顯優(yōu)勢。

Combined with the renovation project of Wuyi Road, this paper discusses the construction technology and quality control of cold recycling base, so as to provide reference experience for the popularization and application of cold recycling base in Kaifeng City. Engineering practice has proved that as long as the scientific organization and strict control, the road performance of cold recycling base is better, and it has more advantages than conventional maintenance methods.

2、準備工作

2. Preparation

再生前的各項準備工作在施工前到位，確保工期正常進行。主要內(nèi)容包括：人員準備、機械準備、材料準備、交通協(xié)調(diào)及后勤保障。

All preparations before regeneration are in place before construction to ensure the normal progress of construction period. The main contents include: Personnel Preparation, machinery preparation, material preparation, traffic coordination and logistics support.

3、材料要求：

3. Material requirements:

水泥選用強度等級為32.5、初凝時間≥3h、終凝時間≤10h且≥6h硅酸鹽或普通硅酸鹽水泥。水泥應具有良好的工作性、低水化、高后期強度、耐久性、耐腐蝕性和抗裂性能。

Portland or ordinary portland cement with strength grade of 32.5, initial setting time ≥ 3h, final setting time ≤ 10h and ≥ 6h is selected. Cement should have good workability, low hydration, high late strength, durability, corrosion resistance and crack resistance.

4、機械要求：

4. Mechanical requirements:

工程施工過程通過再生機組來完成，再生機組包括：冷再生主機、水泥稀漿車、平地機、壓路機等。

The construction process of the project is completed by the regeneration unit, which includes: cold regeneration host, cement slurry truck, grader, roller, etc.

5、人員要求：

5. Personnel requirements:

工程技術人員及機械操作人員應經(jīng)過冷再生培訓并經(jīng)過考核合格后方可上崗。

Engineering and technical personnel and mechanical operators should be trained in cold regeneration and pass the examination before they can take up their posts.
