我們平常所看到的路面改造、路面冷再生都是運(yùn)用冷再生機(jī)的再造技術(shù)，在舊瀝青道路的基礎(chǔ)上，添加一定量的混凝土和粉料，應(yīng)用再生機(jī)對(duì)其進(jìn)行粉碎、加水、攪拌并整形、輾壓和維護(hù)，促使舊道路可以再次交付使用，由于其能夠直接使用原料直接施工，不需要在運(yùn)送新材料，減少了成本費(fèi)用縮短施工期因此在路面更新改造方面?zhèn)涫芄こ添?xiàng)目團(tuán)隊(duì)的青睞，下面冷再生機(jī)租賃小編帶大家一起來看下冷再生機(jī)的工程施工前的檢測(cè)準(zhǔn)備工作。

The road surface renovation and cold recycling that we usually see are all using the recycling technology of cold revitalization. On the basis of the old asphalt road, a certain amount of concrete and powder is added, and a recycling machine is used to crush, water, mix and shape, roll and maintain it, so that the old road can be delivered for use again. Due to its ability to directly use raw materials for construction, there is no need to transport new materials, Reduced costs and shortened construction period, therefore, it is highly favored by the engineering project team in the field of road surface renewal and renovation. Below, let's take a look at the pre construction inspection preparation work of the cold recycling machine rental team.

1、舊瀝青道路彎沉測(cè)試

1. Deflection Testing of Old Asphalt Roads

工程施工前要開展舊路面彎沉檢驗(yàn)，不僅為了判定舊路地基承載能力，還為了對(duì)再造工程施工后的功效與原道路開展對(duì)比分析。

The deflection inspection of the old pavement should be carried out before the construction of the project, not only to determine the bearing capacity of the old road foundation, but also to carry out a comparative analysis of the effect of the reengineering after construction and the original road.

2、檢驗(yàn)明確配合比

2. Clear mix proportion inspection

當(dāng)場(chǎng)銑刨攪拌幾段未添加集料和混凝土的舊道路，實(shí)驗(yàn)室分別平衡取料開展篩分實(shí)驗(yàn)。實(shí)驗(yàn)結(jié)果應(yīng)達(dá)到：粒徑不能超出40mm，粒徑為4.75mm的通過率不低于40%，粒徑為0.6mm的通過率不低于10%，粒徑為0.075mm的通過率宜在3%~20%之間。要是舊料級(jí)配不可以滿足上述標(biāo)準(zhǔn)時(shí)，應(yīng)添加一定規(guī)格、數(shù)目的新瀝青混合料開展配制。

On the spot, milling and mixing several sections of old roads without adding aggregates and concrete were carried out, and the laboratory balanced the materials for screening experiments. The experimental results should achieve: the particle size should not exceed 40mm, the pass rate should not be less than 40% for particles with a particle size of 4.75mm, the pass rate should not be less than 10% for particles with a particle size of 0.6mm, and the pass rate for particles with a particle size of 0.075mm should be between 3% and 20%. If the grading of the old material cannot meet the above standards, a certain specification and quantity of new asphalt mixture should be added for preparation.

3、試驗(yàn)段工程施工

3. Construction of experimental section engineering

配合比完成后，即可開展試驗(yàn)段工程施工；檢驗(yàn)道路長度宜為100m~200m。試驗(yàn)段工程施工應(yīng)包含以下幾點(diǎn)：

After the mix proportion is completed, the construction of the experimental section can be carried out; The length of the inspection road should be between 100m and 200m. The construction of the experimental section project should include the following points:

1）測(cè)算每平米混凝土使用量，并明確混凝土放置的縱、橫向間隔；

1) Calculate the amount of concrete used per square meter and clarify the vertical and horizontal spacing of concrete placement;

2）冷再生機(jī)的工作主要參數(shù)：銑刨、粉碎的深度；行駛的速度；刀具的轉(zhuǎn)速等；

2) The main working parameters of the cold regeneration machine include the depth of milling and crushing; The speed of travel; The speed of the cutting tool, etc;

3）再生機(jī)每行駛1米的需水量及供水車的總數(shù)；

3) The water demand for every 1 meter of operation of the regeneration machine and the total number of water supply vehicles;

4）壓實(shí)工藝主要參數(shù)：機(jī)械設(shè)備組成；壓路機(jī)的規(guī)格型號(hào)、輾壓遍數(shù)、輾壓速度；輾壓時(shí)水分含量的容許誤差；

4) Main parameters of compaction process: composition of mechanical equipment; The specifications and models of the roller, the number of rolling passes, and the rolling speed; The allowable error of moisture content during rolling;

5）優(yōu)化方案后的施工組織方案及工藝等。

5) The optimized construction organization plan and process, etc.

以上就是關(guān)于冷再生機(jī)在對(duì)舊道路改造前的準(zhǔn)備檢車工作，只有事前將路段的檢測(cè)和試驗(yàn)段施工工作做到位，才能對(duì)需要施工路面有一個(gè)數(shù)據(jù)的了解，從而在施工的時(shí)候?qū)ΠY下藥，有針對(duì)性的實(shí)施冷再生改造施工，才能使得改造后的瀝青道路的質(zhì)量和品質(zhì)得到保障。更多相關(guān)事項(xiàng)就來我們網(wǎng)站http://dzjshs.cn咨詢！

The above is about the preparation and inspection work of the cold recycling machine before the renovation of the old road. Only by doing a thorough inspection of the road section and the construction of the test section in advance can we have a data understanding of the road surface that needs to be constructed, so that the targeted implementation of cold recycling renovation construction can ensure the quality and quality of the modified asphalt road.
