隨著我國(guó)公路行業(yè)的發(fā)展，現(xiàn)今我國(guó)早期所修建的公路都已經(jīng)面臨大修以及中修了，每年都有著許多的瀝青路面需要進(jìn)行維修和補(bǔ)建。如果在原有瀝青路面基礎(chǔ)上進(jìn)行修建，那么將會(huì)使得路面被抬高，同時(shí)也會(huì)影響原來(lái)路面的相關(guān)配套設(shè)施的使用，而且這樣的補(bǔ)修方式也會(huì)使得成本投入變高，資源也會(huì)造成浪費(fèi)。然而再生技術(shù)則能使原來(lái)路面的材料再次被投入到路面使用中，同時(shí)也能夠促使路面的性能恢復(fù)，極大程度的符合了可持續(xù)發(fā)展戰(zhàn)略需求。不過(guò)在這之中也需要相關(guān)技術(shù)人員加強(qiáng)研究與探索，限度的發(fā)揮出再生技術(shù)的利用價(jià)值。

　　With the development of China's highway industry, the highways built in the early days of our country are now facing major and medium repairs, and there are many asphalt pavements that need to be repaired and repaired every year. If the construction is carried out on the basis of the original asphalt pavement, it will raise the pavement and also affect the use of related supporting facilities on the original pavement. Moreover, this repair method will increase the cost investment and waste resources. However, regeneration technology can enable the materials of the original road surface to be reused on the road surface, while also promoting the recovery of road performance, which greatly meets the needs of sustainable development strategies. However, it is also necessary for relevant technical personnel to strengthen research and exploration in order to maximize the utilization value of regenerative technology.

　　現(xiàn)今我國(guó)公路總里程呈現(xiàn)出穩(wěn)步增長(zhǎng)的局面，據(jù)交通運(yùn)輸部統(tǒng)計(jì)數(shù)據(jù)顯示，2010年以來(lái)，我國(guó)公路總里程不斷增加，截止到2019年末，我國(guó)公路總里程為501.25萬(wàn)，相對(duì)于去年增長(zhǎng)了16.60萬(wàn)。公路密度52.21/百平方，增加了1.73/百平方。隨著我國(guó)基礎(chǔ)建設(shè)投資、重視程度的增加，高速公路的建設(shè)也呈平穩(wěn)增長(zhǎng)趨勢(shì)，高速公路里程14.96萬(wàn)，增加了0.7萬(wàn)。在公路建設(shè)持續(xù)發(fā)展的狀態(tài)下，交通流量也在不斷加大，這也給瀝青路面帶來(lái)了極大的壓力，早期的瀝青路面損毀較為嚴(yán)重，都面臨著大、中修整。在這之中再生技術(shù)的出現(xiàn)解決了燃眉之急，它的快速、、資源再利用等優(yōu)勢(shì)特點(diǎn)得到了極大青睞。

　　Currently, the total length of highways in China is showing a steady increase. According to statistics from the Ministry of Transport, since 2010, the total length of highways in China has been continuously increasing. As of the end of 2019, the total length of highways in China was 5.0125 million kilometers, an increase of 166000 kilometers compared to last year. The road density is 52.21 kilometers per 100 square kilometers, an increase of 1.73 kilometers per 100 square kilometers. With the increasing investment and emphasis on infrastructure construction in our country, the construction of highways has also shown a steady growth trend, with a total length of 149600 kilometers, an increase of 7000 kilometers. With the continuous development of highway construction, traffic flow is also increasing, which has brought great pressure to asphalt pavement. Early asphalt pavement was severely damaged and faced major and medium repairs. The emergence of regeneration technology has solved the urgent problem, and its advantages such as speed, environmental protection, and resource reuse have been greatly favored.

　　全深式就地冷再生施工工藝主要采用就地冷再生施工設(shè)備對(duì)需要修復(fù)的破損瀝青路面進(jìn)行冷銑刨、破碎以及篩選，再按比例加入新集料、再生結(jié)合料、水泥、石灰、水等，經(jīng)過(guò)常溫?cái)嚢韬?，把這些物料鋪設(shè)路面上，再經(jīng)碾壓后成型。這一施工工藝是需要一整套工序在現(xiàn)場(chǎng)有序的完成。其中全深式就地冷再生包含著瀝青材料層與非瀝青材料層。

Then, new aggregates, recycled binders, cement, lime, water, etc. are added in proportion. After mixing at room temperature, these materials are laid on the pavement and then compacted to form. This construction process requires a complete set of procedures to be completed in an orderly manner on site. The full depth in-situ cold regeneration includes an asphalt material layer and a non asphalt material layer.

　　In the construction process of fully deep on-site cold recycling base, it can effectively save resources and promote environmental protection. It can recycle and reuse materials that were originally used in asphalt pavement construction during the construction process, especially some sand and gravel materials, avoiding the waste caused by the re exploitation of such resources. Recycling this series of materials can also prevent them from being discarded and occupying land resources, causing environmental pollution.

　　(4)提高路面的平整度

　　全深式就地冷再生施工工藝與質(zhì)量控制措施

　　Construction technology and quality control measures for fully deep on-site cold recycling

　　(1)全深式就地冷再生施工工藝原理

　　(1) Principle of Full Depth On site Cold Recycling Construction Technology

　　全深式就地冷再生施工工藝需要將瀝青路面中全部厚度的瀝青面層與預(yù)定比例匯總的下臥層統(tǒng)一進(jìn)行粉碎與攪拌融合在一起，以此來(lái)提供升級(jí)的均勻基層材料的維修技術(shù)。若舊材料中沒(méi)有足夠的力學(xué)性能與結(jié)構(gòu)強(qiáng)度承載預(yù)期中的荷載，那么就需要在其中加入新的集料，同時(shí)也需要按照一定的比例加入定量的化學(xué)穩(wěn)定劑，以此來(lái)達(dá)到預(yù)期的效果。

　　The full depth on-site cold recycling construction process requires the uniform crushing and mixing of the entire thickness of asphalt surface layer in the asphalt pavement with the predetermined proportion of the underlying layer, in order to provide upgraded and uniform base material maintenance technology. If the old material does not have sufficient mechanical properties and structural strength to bear the expected load, new aggregates need to be added to it, and a certain proportion of chemical stabilizers need to be added to achieve the expected effect.

　　冷再生機(jī)租賃

　　Cold Recycling Machine Rental

　　在全深式就地冷再生施工工藝操作中需要再生層的下承層完好無(wú)損，且它的厚度應(yīng)不低于10cm，同時(shí)也需要盡可能的滿足結(jié)構(gòu)層面所需的強(qiáng)度需求。在全深式就地冷再生技術(shù)中，其中厚度對(duì)于單一壓實(shí)層在使用水泥與石灰時(shí)要把厚度控制在15~25cm之間。在使用乳化瀝青以及泡沫瀝青材質(zhì)時(shí)厚度則需要控制在8~16cm之間。單層冷再生層面若厚度過(guò)厚那么在壓實(shí)該層面時(shí)就會(huì)出現(xiàn)問(wèn)題，導(dǎo)致相關(guān)器械無(wú)法壓實(shí)該層面，特別在越下方的越不易被壓實(shí)。在滿足壓實(shí)度要求的再生層中，除了應(yīng)在平均壓實(shí)度方面達(dá)到要求之外，表層5cm與底部5cm之間的密度差距應(yīng)控制在2%以內(nèi)。當(dāng)然在施工過(guò)程中也可以選擇雙層再生，這就需要把存有一定厚度的表層材料進(jìn)行銑刨，然后再對(duì)下面的路面進(jìn)行就地冷再生，接著將銑刨的表層材料進(jìn)行攪拌融合再進(jìn)行鋪設(shè)。雙層再生層面鋪設(shè)不受之前所描述的厚度的限制。

　　In the operation of the fully deep on-site cold recycling construction process, it is necessary to ensure that the lower layer of the recycling layer is intact, and its thickness should not be less than 10cm. At the same time, it is also necessary to meet the strength requirements of the structural layer as much as possible. In the fully deep in-situ cold recycling technology, the thickness of a single compacted layer should be controlled between 15-25cm when using cement and lime. When emulsified asphalt and foam asphalt materials are used, the thickness should be controlled within 8~16cm. If the thickness of the single-layer cold recycling layer is too thick, there will be problems when compacting the layer, causing the relevant equipment to be unable to compact the layer, especially the lower the layer, the less likely it is to be compacted. In the recycled layer that meets the compaction requirements, in addition to meeting the requirements in terms of average compaction, the density difference between the surface 5cm and the bottom 5cm should be controlled within 2%. Of course, double-layer regeneration can also be chosen during the construction process, which requires milling and planing the surface material with a certain thickness, and then on-site cold regeneration of the underlying road surface. Then, the milled surface material is mixed and fused before laying. The double-layer regeneration layer is not limited by the thickness previously described.

　　(2)全深式就地冷再生施工中所使用的機(jī)械設(shè)施設(shè)備

　　(2) Mechanical facilities and equipment used in the construction of fully deep on-site cold recycling

　　在運(yùn)用全深式就地冷再生施工工藝時(shí)不需要使用大型機(jī)械設(shè)備，主要使用的機(jī)械設(shè)備包含再生設(shè)備、穩(wěn)定劑添加設(shè)備、平地機(jī)以及壓路機(jī)。

　　When using the full depth on-site cold recycling construction process, large mechanical equipment is not required. The main mechanical equipment used includes recycling equipment, stabilizer addition equipment, grader, and roller.

　　冷再生機(jī)租賃主要的功能就在于粉碎與回收材料，它在全深式就地冷再生施工工藝操作中占據(jù)著主要的位置。冷再生機(jī)租賃可以粉碎、攪拌30cm厚度的瀝青路面及下臥層材料。在冷再生機(jī)設(shè)備中的滾筒中應(yīng)該裝置可以進(jìn)行替換的碳化鎢齒刀具，同時(shí)還應(yīng)裝有人力操作與自動(dòng)操作的裝置，另外這一設(shè)備也應(yīng)可以有效的調(diào)節(jié)滾筒轉(zhuǎn)動(dòng)速度，以此來(lái)適應(yīng)不同厚度材質(zhì)的粉碎與攪拌。

　　The main function of leasing a cold recycling machine is to crush and recycle materials, and it occupies a major position in the operation of the full depth on-site cold recycling construction process. Cold recycling machine rental can crush and mix asphalt pavement and underlying layer materials with a thickness of 30cm. In the cold regeneration equipment, tungsten carbide toothed cutting tools that can be replaced should be installed in the drum, and manual and automatic operation devices should also be installed. In addition, this equipment should be able to effectively adjust the rotation speed of the drum to adapt to the crushing and mixing of materials with different thicknesses.

　　另外再生材料中若含水量沒(méi)有達(dá)到既定標(biāo)準(zhǔn)那么就需要讓其在通過(guò)干燥的過(guò)程中達(dá)到既定含水量標(biāo)準(zhǔn)，另外若再生材料過(guò)干，那么也需要補(bǔ)足水分。冷再生機(jī)就可以配備相應(yīng)的水噴頭對(duì)再生材料添加水分，在對(duì)再生材料粉碎以及攪拌的過(guò)程中也可以進(jìn)行水分的添加，同時(shí)在這時(shí)添加水分也能更好的進(jìn)行估計(jì)。

　　In addition, if the moisture content in the recycled material does not meet the established standard, it needs to be allowed to reach the established moisture content standard during the drying process. In addition, if the recycled material is too dry, it also needs to be replenished with moisture. The cold regeneration machine can be equipped with corresponding water nozzles to add moisture to the regenerated material. During the process of crushing and stirring the regenerated material, moisture can also be added, and adding moisture at this time can better estimate.

　　當(dāng)在再生材料中添加穩(wěn)定劑時(shí)，若添加的穩(wěn)定劑為粉狀物，那么就需要定量攤鋪撒料。干粉穩(wěn)定劑可以在粉碎瀝青層路面時(shí)加入也可以在冷再生機(jī)攪拌再生材料之前加入。不夠粉狀物的穩(wěn)定劑會(huì)受到天氣因素的影響，另外在定量攤鋪撒料操作中也易于產(chǎn)生塵霧，對(duì)施工操作人員和環(huán)境有著極大的影響。當(dāng)穩(wěn)定劑為液體狀態(tài)加入到冷再生機(jī)中時(shí)，需要隨帶的計(jì)算機(jī)液體添加系統(tǒng)對(duì)各個(gè)液體添加量進(jìn)行精準(zhǔn)計(jì)算，同時(shí)也需要有一個(gè)與冷再生機(jī)前進(jìn)速度相關(guān)的正互鎖系統(tǒng)，從而使得液體穩(wěn)定劑的添加量跟隨著冷再生機(jī)運(yùn)行的變化而發(fā)生變化。

　　When adding stabilizers to recycled materials, if the stabilizer added is in powder form, it is necessary to spread the material in a quantitative manner. Dry powder stabilizer can be added during the crushing of asphalt pavement or before mixing the recycled material in the cold recycling machine. Stabilizers that are not powdery enough will be affected by weather factors, and in addition, dust and mist are easily generated during quantitative paving and spreading operations, which have a great impact on construction operators and the environment. When the stabilizer is added to the cold regeneration machine in a liquid state, it is necessary to have a computerized liquid addition system to accurately calculate the amount of each liquid added. At the same time, a positive interlock system related to the speed of the cold regeneration machine is also required, so that the amount of liquid stabilizer added changes with the operation of the cold regeneration machine.

　　當(dāng)冷再生機(jī)完成粉碎與攪拌融合任務(wù)后就需要運(yùn)用到平地機(jī)進(jìn)行鋪設(shè)與整形操作。在再生材料鋪設(shè)中對(duì)其鋪設(shè)的厚度有著嚴(yán)謹(jǐn)?shù)男枨螅虼嗽趬郝窓C(jī)的選擇上就會(huì)偏重、大。因此經(jīng)過(guò)壓路機(jī)的作用能夠讓再生材料的鋪設(shè)更加的完整、自然，能夠圓滿完成自身所需要完成的任務(wù)量，以此保證所鋪設(shè)的路面能夠滿足使用需求，能夠承載預(yù)期設(shè)計(jì)時(shí)的載重、荷載。

　　After the cold recycling machine completes the crushing and mixing fusion tasks, it needs to be applied to the leveling machine for laying and shaping operations. There is a strict requirement for the thickness of recycled material laying, so the selection of rollers will be biased and large. Therefore, through the action of the roller, the laying of recycled materials can be more complete and natural, and the required amount of tasks can be successfully completed to ensure that the road surface can meet the usage needs and bear the expected design load.

　　(3)全深式就地冷再生施工工藝技術(shù)

　　(3) Full depth on-site cold recycling construction technology

　　要進(jìn)行施工放樣，檢查全深式就地冷再生相關(guān)機(jī)械設(shè)施設(shè)備的準(zhǔn)備情況，以及備料情況，接著再進(jìn)行定格操作、鋪設(shè)水泥，在這一步驟中需要對(duì)水泥的用量進(jìn)行細(xì)致的檢查。接著再使用冷再生機(jī)加水進(jìn)行攪拌工作，這一步驟也需要檢查水泥劑量與用水量，一定要按照規(guī)定的標(biāo)準(zhǔn)以及需求使用相關(guān)材料，當(dāng)攪拌完成后就將其鋪設(shè)路面，通過(guò)使用羊角碾進(jìn)行初步碾壓，在碾壓過(guò)程中需要檢測(cè)厚度，厚度也需要按照相關(guān)要求進(jìn)行操作。接下來(lái)就使用平地機(jī)進(jìn)行壓平操作，這一步驟中需要補(bǔ)充灑水，同時(shí)施工人員要配合平地機(jī)進(jìn)行壓平操作，避免一些地方操作漏失。然后再運(yùn)用光輪壓路機(jī)對(duì)平地機(jī)壓過(guò)的路面進(jìn)行復(fù)壓，在復(fù)壓過(guò)后膠輪壓路機(jī)要再壓一次，同時(shí)在這個(gè)過(guò)程中要檢測(cè)路面各個(gè)指標(biāo)是否達(dá)到了設(shè)計(jì)要求。當(dāng)以上操作都符合操作規(guī)范與各項(xiàng)指標(biāo)后就需要將修復(fù)的這段瀝青路面安置防撞筒覆蓋土工布進(jìn)行養(yǎng)生，以便之后更好的投入到使用中。

　　Firstly, construction layout should be carried out to check the preparation and material preparation of the mechanical facilities and equipment related to the full depth on-site cold recycling. Then, the fixed frame operation and cement laying should be carried out, and the amount of cement used should be carefully checked in this step. Next, the cold recycling machine is used to add water for mixing work. This step also requires checking the cement dosage and water consumption. It is necessary to use relevant materials according to the prescribed standards and requirements. After mixing is completed, it is laid on the road surface and preliminarily rolled using a sheep horn roller. During the rolling process, the thickness needs to be checked and operated according to relevant requirements. The next step is to use a grader for flattening operation, which requires additional watering. At the same time, construction personnel should cooperate with the grader to carry out flattening operation to avoid operational errors in some areas. Then, the smooth wheeled roller is used to re press the road surface that has been flattened by the grader. After re pressing, the rubber wheeled roller needs to press again for the last time, and during this process, it is necessary to check whether the various indicators of the road surface meet the design requirements. When all the above operations comply with the operating specifications and various indicators, it is necessary to install a safety anti-collision tube on the repaired asphalt pavement and cover it with geotextile for curing, so as to better put it into use in the future.

　　在運(yùn)用全深式就地冷再生施工工藝時(shí)需要將機(jī)械設(shè)備配備好，按照施工過(guò)程中所需要運(yùn)用到的各項(xiàng)機(jī)械設(shè)備來(lái)按套配備，以此保證該工藝在施展時(shí)井然有序，避免手忙腳亂現(xiàn)象的發(fā)生。當(dāng)建設(shè)施工過(guò)程中所需的設(shè)施設(shè)備到位后就需要對(duì)所需要使用到的各種材料用量進(jìn)行計(jì)算。例如在水泥穩(wěn)定劑通過(guò)干粉狀加入時(shí)，應(yīng)先計(jì)算出所需要摻和多少數(shù)量的水泥。公式為:水泥用量(kg/㎡)=壓實(shí)厚度(m)×干容量(kg/m?)×壓實(shí)度(%)×水泥劑量(%)/(1+水泥劑量(%))。通過(guò)這一公式來(lái)計(jì)算水泥用量，再推算水泥穩(wěn)定劑用量。

　　When using the full depth on-site cold recycling construction process, it is necessary to first equip the mechanical equipment according to the various mechanical equipment required during the construction process, in order to ensure that the process is carried out in an orderly manner and avoid the occurrence of flustered situations. After the necessary facilities and equipment are in place during the construction process, it is necessary to calculate the amount of various materials needed. For example, when adding cement stabilizer in dry powder form, the required amount of cement should be calculated first. The formula is: cement dosage (kg/㎡)=compacted thickness (m) × maximum dry capacity (kg/m?) × compaction degree (%) × cement dosage (%)/(1+cement dosage (%)). Calculate the amount of cement and then calculate the amount of cement stabilizer using this formula.

　　在全深式就地冷再生施工工藝操作過(guò)程中還能夠運(yùn)用到一種預(yù)布材料，其中預(yù)布水泥需要對(duì)預(yù)布的長(zhǎng)度進(jìn)行控制，以此保障冷再生機(jī)在攪拌再生材料時(shí)能夠正常運(yùn)行。另外也需要依據(jù)冷再生機(jī)的行駛速度以及路面坡度、橫坡的大小來(lái)確定預(yù)布的長(zhǎng)度，在一般情況中預(yù)布長(zhǎng)度為80~150m，在冷再生機(jī)攪拌再生材料的同時(shí)進(jìn)行撒布操作，避免過(guò)往車輛在行駛過(guò)程中車速過(guò)快帶動(dòng)預(yù)布造成污染，從而也對(duì)材料造成一定的損失、浪費(fèi)。

　　In the operation process of the full depth on-site cold recycling construction technology, a pre laid material can also be used, in which the pre laid cement needs to be controlled in length to ensure the normal operation of the cold recycling machine when mixing recycled materials. In addition, the length of the pre cloth needs to be determined based on the driving speed of the cold recycling machine, as well as the size of the road slope and cross slope. In general, the pre cloth length is 80-150m. It is best to carry out the spreading operation while the cold recycling machine is mixing the recycled materials to avoid pollution caused by passing vehicles driving the pre cloth too fast during the driving process, which may also cause certain losses and waste to the materials.

　　在運(yùn)用全深式就地冷再生施工工藝修補(bǔ)路面的過(guò)程中，冷再生機(jī)能夠處理的寬度一般會(huì)與路面的寬度之間存在著一定的差距，因此就需要多次進(jìn)行粉碎操作來(lái)處理需要修補(bǔ)的瀝青路面，基于此就會(huì)使得路面出現(xiàn)多個(gè)縱向接頭以及一些搭接現(xiàn)象。

　　In the process of using the full depth on-site cold recycling construction technology to repair the road surface, there is generally a certain gap between the width that the cold recycling machine can handle and the width of the road surface. Therefore, multiple crushing operations are required to process the asphalt road surface that needs to be repaired, which will result in multiple longitudinal joints and some overlapping phenomena on the road surface.

　　其中冷再生機(jī)的工作速度對(duì)于之中能夠修補(bǔ)多少瀝青路面存在著極大的影響。在這之中瀝青路面的厚度、硬度以及需要加入到再生材料中的下臥層的厚度、再生材料的要求和冷再生機(jī)的生產(chǎn)能力等等都會(huì)對(duì)冷再生機(jī)的工作效率造成一定的影響。

　　The working speed of cold regeneration has a significant impact on how much asphalt pavement can be repaired in a day. The thickness and hardness of the asphalt pavement, as well as the thickness of the underlying layer that needs to be added to the recycled material, the requirements of the recycled material, and the production capacity of the cold recycling machine will all have a certain impact on the efficiency of the cold recycling machine.

　　結(jié)語(yǔ)

　　Conclusion

　　現(xiàn)今在我國(guó)將全深式就地冷再生施工工藝廣泛運(yùn)用到了瀝青路面的修整中，全深式就地冷再生施工工藝的使用節(jié)約了大量的成本支出，同時(shí)對(duì)于資源浪費(fèi)現(xiàn)象也能夠有效的解決，它其中的原有瀝青路面材料二次回收利用對(duì)于解決環(huán)境污染與資源匱乏現(xiàn)象有著極大的作用。

The use of the fully deep on-site cold recycling construction technology saves a lot of cost expenditures and can effectively solve the problem of resource waste. The secondary recycling of the original asphalt pavement material plays a great role in solving environmental pollution and resource scarcity.
