路面冷再生機(jī)其就地冷再生施工優(yōu)點(diǎn)

近年來(lái)，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(guò)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(jiàn)。
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.
水泥就地冷再生主要解決瀝青路面基層損壞問(wèn)題，早在二十世紀(jì)就在歐洲和美國(guó)得到了廣泛應(yīng)用。主要是指充分利用現(xiàn)有的瀝青路面材料（必要時(shí)，作為新的骨料），并按一定比例加入一定量的水泥和水。在自然溫度下，材料通過(guò)特定的機(jī)器連續(xù)地銑削、破碎、混合、鋪砌和壓實(shí)，從而重建所需的性能。新基層(底基層)的工作過(guò)程質(zhì)量。該技術(shù)以其低成本、出色率、高質(zhì)量、高環(huán)保等優(yōu)點(diǎn)吸引了業(yè)界的關(guān)注和青睞。然而，局部材料的原因不可避免地帶來(lái)了一些缺陷。
Cement in situ cold recycling mainly solves the problem of asphalt pavement base damage, and has been widely used in Europe and the United States as early as the 20th century. It mainly refers to making full use of the existing asphalt pavement materials (as new aggregates if necessary) and adding a certain amount of cement and water in a certain proportion. At natural temperature, materials are continuously milled, crushed, mixed, paved and compacted by specific machines to rebuild the required properties. Work process quality of new base (subbase). This technology has attracted the attention and favor of the industry with its advantages of low cost, high efficiency, high quality and high environmental protection. However, the local material causes inevitably bring some defects.
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?，并為施工進(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?？梢孕纬墒┕さ暮駥?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(guò)舊路的厚度、密度和比來(lái)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.
高環(huán)保
High environmental protection
路面冷再生機(jī)其就地冷再生施工采用傳統(tǒng)的公路養(yǎng)護(hù)方法，瀝青路面和基層材料的浪費(fèi)很大，環(huán)境受到污染。同時(shí)，大量的新材料的獲取也會(huì)造成資源和環(huán)境的破壞。采用水泥就地冷再生技術(shù)可以完全利用原材料來(lái)避免上述問(wèn)題。它不僅節(jié)約了大量的投資，而且更有利于環(huán)境保護(hù)，因此被稱(chēng)為“綠色”施工技術(shù)。
The local cold recycling construction of pavement cold recycling machine adopts the traditional highway maintenance method, which wastes a lot of asphalt pavement and base course materials and pollutes the environment. At the same time, the acquisition of a large number of new materials will also cause damage to resources and environment. The above problems can be avoided by using the cement in-situ cold regeneration technology. It not only saves a lot of investment, but also is more conducive to environmental protection, so it is called "green" construction technology.
