路面冷再生機(jī)其就地冷再生施工優(yōu)點(diǎn)
來源：http://kqj188.com/ 日期：2021-08-19 發(fā)布人：
近年來，隨著交通運(yùn)輸業(yè)的快速發(fā)展，大量的瀝青混凝土道路已建成。經(jīng)過多年的運(yùn)行，許多設(shè)計(jì)水平低、承載能力差的公路受到了不同程度的損壞，為公路的養(yǎng)護(hù)和養(yǎng)護(hù)提出了新的課題。本文結(jié)合就地冷再生施工的實(shí)踐，結(jié)合工程實(shí)踐，提出了就地冷再生施工的總結(jié)和意見。
In recent years, with the rapid development of China's transportation industry, a large number of asphalt concrete roads have been built all over the country. After years of operation, many highways with low design level and poor bearing capacity have been damaged to varying degrees, which puts forward a new topic for highway maintenance. Combined with the practice of in-situ cold regeneration construction and engineering practice, this paper puts forward the summary and opinions of in-situ cold regeneration construction.
優(yōu)點(diǎn)
advantage
與傳統(tǒng)的公路養(yǎng)護(hù)方法相比，水泥就地冷再生具有許多優(yōu)點(diǎn)。
Compared with traditional highway maintenance methods, cement in situ cold recycling has many advantages.
成本低
Low cost
由于舊水泥在水泥冷再生中的應(yīng)用，降低了路面養(yǎng)護(hù)過程中一些新材料的挖掘、運(yùn)輸、浪費(fèi)和購(gòu)置成本，大大降低了成本。與傳統(tǒng)方法相比，道路水泥的成本可降低20%～40%，厚度越深，成本越高。水泥現(xiàn)場(chǎng)冷再生技術(shù)可以大大降低工程造價(jià)，與傳統(tǒng)的養(yǎng)護(hù)方案形成鮮明的對(duì)比。
Due to the application of old cement in cement cold recycling, the excavation, transportation, waste and purchase cost of some new materials in the process of pavement maintenance are reduced, and the cost is greatly reduced. Compared with traditional methods, the cost of road cement can be reduced by 20% ~ 40%. The deeper the thickness, the higher the cost. The on-site cold recycling technology of cement can greatly reduce the project cost, which is in sharp contrast to the traditional maintenance scheme.
進(jìn)度快、效率高
Fast progress and high efficiency
水泥就地冷再生的施工可以通過加、銑、斷、混、攤、壓來完成，從而簡(jiǎn)化了施工工序，縮短了施工工期。使用水泥現(xiàn)場(chǎng)冷再生機(jī)，每天可完成6000平方米至9000M2的工作量。與傳統(tǒng)的道路養(yǎng)護(hù)、運(yùn)輸、垃圾填埋（不到2000平方米）相比，不可一日而語。
The construction of cement local cold regeneration can be completed by adding, milling, breaking, mixing, spreading and pressing, which simplifies the construction process and shortens the construction period. Using the cement on-site cold regenerator, the workload of 6000 square meters to 9000m2 can be completed every day. Compared with the traditional road maintenance, transportation and landfill (less than 2000 square meters), it can not be said in a day.
此外，在常溫下，只要不進(jìn)行雨雪天氣施工，使用的材料只有水泥和其他添加劑，減少外部攪拌和運(yùn)輸?shù)挠绊懀槭┕みM(jìn)度提供較大幫助。
In addition, at normal temperature, as long as the construction is not carried out in rainy and snowy weather, only cement and other additives are used to reduce the impact of external mixing and transportation and provide great help to the construction progress.
質(zhì)量好，易于控制
Good quality and easy to control
水泥路面原位冷再生可根據(jù)舊路面材料在不同道路上的實(shí)際情況設(shè)計(jì)。選擇不同的添加劑，配比準(zhǔn)確。保證了再生材料的優(yōu)良質(zhì)量和施工質(zhì)量。可以形成施工的厚實(shí)均勻的基座，從而保證維修后道路的使用周期。
The in-situ cold recycling of cement pavement can be designed according to the actual situation of old pavement materials on different roads. Different additives are selected and the ratio is accurate. The excellent quality and construction quality of recycled materials are guaranteed. It can form a thick and uniform base for construction, so as to ensure the service life of the road after maintenance.
此外，由于水泥原位再生完全是水泥添加劑，它可以通過舊路的厚度、密度和比來計(jì)算1M2水泥冷再生混合物所需的水泥用量，并計(jì)算每袋水泥的攤鋪面積，然后劃格按平方布水泥,控制方法簡(jiǎn)單,易于接受控制。
In addition, because the in-situ regeneration of cement is completely a cement additive, it can calculate the cement dosage required for 1m2 cement cold regeneration mixture through the thickness, density and ratio of the old road, calculate the paving area of each bag of cement, and then divide the cement according to square. The control method is simple and easy to accept control.
