冷再生技術在舊路面處理方面的應用

冷再生技術在原有公路實際情況基礎上進行施工◕•✘▩,不但對於原有路基沒有影響◕•✘▩,還有利於提高原公路等級◕•✘▩,同時鋪層厚度控制得更加準確•╃•。下面冷再生機出租廠家來講講冷再生技術在舊路面處理方面的應用·•!
The cold regeneration technology is constructed on the basis of the actual conditions of the original highway, which not only has no impact on the original subgrade, but also is conducive to improving the grade of the original highway, and at the same time, the layer thickness is controlled more accurately. Let's talk about the application of cold recycling technology in the treatment of old pavement!
在進行路面冷再生施工的過程中◕•✘▩,先應按照設計方案要求的厚度刨除現有路面◕•✘▩,銑刨機應保持勻速執行◕•✘▩,速度控制在4—6m/min左右◕•✘▩,銑刨完成的路面不得存在團結成塊現象•╃•。
In the process of cold pavement regeneration construction, the existing pavement shall be planed according to the thickness required by the design scheme. The milling machine shall operate at a constant speed, and the speed shall be controlled at about 4-6 m/min. The milled pavement shall not be united into blocks.
舊有路面面層材料在破碎之後◕•✘▩,應對其進行篩分◕•✘▩,合理控制回收集料的尺寸與級配◕•✘▩,避免存在過大粒徑◕•✘▩,並運送至指定拌合地點集中堆放•╃•。
After the old pavement surface material is broken, it should be screened, and the size and grading of recycled aggregate should be controlled reasonably to avoid excessive particle size, and transported to the designated mixing site for centralized stacking.
其次是修整下承層◕•✘▩,將表面存在的雜物清除乾淨◕•✘▩,調整路拱坡度◕•✘▩,若存在坑洞│╃╃··、脫皮等現象◕•✘▩,應及時進行處理◕•✘▩,避免影響與再生結構層的粘結效能•╃•。待其質量驗收合格之後◕•✘▩,將乳化瀝青透油層均勻撒佈至下承層表面•╃•。
The second is to trim the lower bearing layer, remove the sundries on the surface, adjust the slope of the road arch, and timely deal with the potholes, peeling and other phenomena to avoid affecting the bonding performance with the recycled structural layer. After the quality acceptance, evenly spread the emulsified asphalt prime coat onto the surface of the lower bearing layer.

若原路面材料級配無法達到冷再生技術施工標準時◕•✘▩,應當加入一定的新集料◕•✘▩,所選取集料技術指標應符合相關技術規範•╃•。
If the gradation of raw pavement materials cannot meet the construction standard of cold recycling technology, a certain amount of new aggregate shall be added, and the selected aggregate technical indicators shall comply with relevant technical specifications.
為提升再生結構層早期強度◕•✘▩,通常情況下再生混合料中應摻入適量水泥◕•✘▩,宜採用初凝時間較長的水泥材料•╃•。在充分掌握各項原材料效能指標的基礎上◕•✘▩,透過多次試驗確定佳配合比例◕•✘▩,確保滿足公路工程施工的要求•╃•。
In order to improve the early strength of the recycled structural layer, in general, the recycled mixture should be mixed with an appropriate amount of cement, and the cement material with a long initial setting time should be used. On the basis of fully mastering the performance indicators of various raw materials, the best mix proportion is determined through multiple tests to ensure that the requirements of highway engineering construction are met.
此外材料的選取和比例應該適當•╃•。施工方須根據整個路面的混凝土結構狀況來界定佳材料混入比例◕•✘▩,以達到大限度提升成型路面剛性的作用•╃•。例如在選取骨料時◕•✘▩,應注意骨料好要大於5mm◕•✘▩,在材料配比中至少要佔到四成以上的重量•╃•。做到這一點才能保證成型路面的質量•╃•。
In addition, the selection and proportion of materials should be appropriate. The construction party shall define the mixing proportion of good materials according to the concrete structure of the whole pavement, so as to achieve the function of improving the rigidity of the formed pavement to a large extent. For example, when selecting aggregates, it should be noted that the quality of aggregates should be greater than 5mm, accounting for at least 40% of the weight in the material mix. Only by doing this can the quality of the formed pavement be guaranteed.
冷再生技術的不斷改善可以很圓滿的解決這些問題◕•✘▩,在不禁止公路通行的前提下◕•✘▩,完成道路的修整工作•╃•。更好的促進了經濟的發展•╃•。更多相關內容◕•✘▩,就來我們網站http://www.soundaffectsdc.com進行諮詢吧·•!
