冷再生机是一种高效率、多用途、集铣刨、破碎、拌合于一体的路面施工设备，其主要用于旧沥青混凝土路面的铣刨以及添加沥青等粘结材料和水的再生利用。除此功能外，其同时具备土壤稳定路拌施工的强大功能，不容小视。

　　Cold recycling machine is a high-efficiency, multi-purpose road construction equipment that integrates milling, crushing, and mixing. It is mainly used for milling old asphalt concrete pavement, adding bonding materials such as asphalt, and recycling water. In addition to this function, it also has the powerful function of soil stabilization and road mixing construction, which should not be underestimated.

　　一、虽然土壤置换作业已经不能代表当前的工艺水平，但是人们仍旧经常使用。再生机以其强有力的铣刨和拌合转子将预撒布的粘结剂，例如石灰或水泥，拌入承载能力较差的现有土壤中，工作深度往往可达1250px以上，将其就地转换成优质的筑路材料，生成均匀的土与粘结剂的混合物，具有很高的抗压、抗拉、抗剪强度，抗水性、抗冻性及很高的体积稳定性。典型的应用包括筑路、停车场、体育场地、工业园区的建设或者机场、大坝、填方工程的施工建设。土壤稳定明显优于土壤置换作业，它减少卡车的运输次数，缩短工期，降低资源消耗和碳排放。这种快速、环保的工艺，避免了昂贵的土壤置换作业。

　　1、 Although soil replacement operations can no longer represent the current level of technology, they are still frequently used by people. The recycling machine uses its powerful milling and mixing rotor to mix pre spread binders, such as lime or cement, into existing soil with poor bearing capacity. The working depth can often reach 1250px or more, converting them into high-quality road materials on site, generating a uniform mixture of soil and binder, with high compressive, tensile, shear strength, water resistance, frost resistance, and high volume stability. Typical applications include the construction of roads, parking lots, sports venues, industrial parks, or the construction of airports, dams, and fill projects. Soil stability is significantly better than soil replacement operations, as it reduces the frequency of truck transportation, shortens the construction period, and lowers resource consumption and carbon emissions. This fast and environmentally friendly process avoids expensive soil replacement operations.

　　二、均化处理：再生机在不加入任何粘结剂的情况下，采用强有力的铣刨和拌合转子，将现有土壤颗粒化并使之松散，以便均化土壤。平地机用于处理经过稳定后的均匀土粒，通过压路机有效压实。三、石灰稳定：预先撒布石灰，使用再生机将其与现有土壤搅拌，生成均匀的混合料，平地机整平，压路机压实。四、水泥稳定：预先使用水泥撒布车或人工摊铺水泥，紧跟一台水车与再生机相连，通过再生机将水泥与现有土壤搅拌，水通过喷洒梁喷洒到再生机拌合室内，平地机整平后，用压路机压实。

　　2、 Homogenization treatment: The regeneration machine uses powerful milling and mixing rotors to granulate and loosen the existing soil without adding any binder, in order to homogenize the soil. A grader is used to process uniformly stabilized soil particles, which are effectively compacted by a roller. 3、 Lime stabilization: Spread lime in advance, mix it with existing soil using a recycling machine to produce a uniform mixture, level it with a grader, and compact it with a roller. 4、 Cement stabilization: Cement is pre spread using a cement spreader or manually laid, followed by a water truck connected to a recycling machine. The cement is mixed with existing soil through the recycling machine, and water is sprayed into the mixing room of the recycling machine through a spray beam. After leveling with a grader, it is compacted with a roller.

　　因此，使用再生机进行土壤稳定施工，就是将劣质土壤变成优质筑路材料，避免了土壤置换带来的昂贵费用，其施工进度快，易于控制土壤含水量，施工效果好，必将成为土壤稳定施工的优选设备。

　　Therefore, using a regeneration machine for soil stabilization construction is to turn inferior soil into high-quality road building materials, avoiding the expensive cost of soil replacement. Its construction progress is fast, easy to control soil moisture content, and construction effect is good. It will become the preferred equipment for soil stabilization construction.
