在道路建設(shè)與養(yǎng)護(hù)領(lǐng)域，冷再生技術(shù)憑借出色、環(huán)保、經(jīng)濟(jì)等優(yōu)勢(shì)，成為道路修復(fù)與改造的重要手段。而冷再生機(jī)租賃服務(wù)的興起，為各類道路工程提供了靈活便捷的施工設(shè)備解決方案。那么，租賃冷再生機(jī)究竟能處理哪些路面呢？這一問題關(guān)乎道路工程的施工選擇與效果，值得深入探討。

　　In the field of road construction and maintenance, cold recycling technology has become an important means of road repair and renovation due to its advantages of high efficiency, environmental protection, and economy. The rise of cold recycling machine rental services has provided flexible and convenient construction equipment solutions for various road projects. So, what types of roads can be treated by leasing a cold recycling machine? This issue concerns the construction selection and effectiveness of road engineering, and is worth further exploration.

　　一、瀝青路面的病害修復(fù)

　　1、 Repair of asphalt pavement diseases

　　（1） Rutting treatment

　　隨著車輛荷載的反復(fù)突出，瀝青路面容易出現(xiàn)車轍病害，尤其是在高速公路、城市主干道等交通流量大的路段。冷再生機(jī)通過銑刨、破碎等功能，將車轍深度較深的路面進(jìn)行破碎處理，再添加適量的新瀝青混合料、再生劑等材料，經(jīng)過攪拌、攤鋪和壓實(shí)，重新形成平整、穩(wěn)定的路面結(jié)構(gòu)。這種處理方式能夠有效恢復(fù)路面的平整度，提升道路的行車舒適性與安全性，同時(shí)充分利用舊路面材料，降低工程成本。

　　With the repeated rolling of vehicle loads, asphalt pavement is prone to rutting diseases, especially in high traffic sections such as highways and urban main roads. The cold recycling machine uses functions such as milling and crushing to crush the road surface with deep ruts, and then adds an appropriate amount of new asphalt mixture, rejuvenator and other materials. After mixing, paving and compaction, it forms a smooth and stable road structure again. This processing method can effectively restore the smoothness of the road surface, improve the driving comfort and safety of the road, and make full use of old road materials to reduce engineering costs.

　　（二）裂縫修復(fù)

　?。?） Crack repair

　　瀝青路面裂縫是常見的病害之一，包括橫向裂縫、縱向裂縫和網(wǎng)狀裂縫等。冷再生機(jī)可以對(duì)存在裂縫的路面區(qū)域進(jìn)行銑刨，去除表面已損壞的瀝青層。隨后，通過添加新的粘結(jié)材料和再生混合料，將新舊材料充分?jǐn)嚢杌旌?，使路面結(jié)構(gòu)重新形成整體。這不僅能封閉裂縫，防止水分進(jìn)一步滲入路基，還能增強(qiáng)路面的整體強(qiáng)度和抗裂性能，延長(zhǎng)路面的使用壽命。

　　Asphalt pavement cracks are one of the common diseases, including transverse cracks, longitudinal cracks, and mesh cracks. The cold recycling machine can mill and remove the damaged asphalt layer on the surface of road areas with cracks. Subsequently, by adding new bonding materials and recycled mixtures, the new and old materials are thoroughly mixed and blended to reshape the road surface structure as a whole. This not only seals cracks and prevents moisture from further seeping into the roadbed, but also enhances the overall strength and crack resistance of the pavement, extending its service life.

　　（三）表面磨損與老化處理

　　（3） Surface wear and aging treatment

　　長(zhǎng)期使用的瀝青路面，表面會(huì)因車輛摩擦、紫外線照射、雨水侵蝕等因素出現(xiàn)磨損、老化現(xiàn)象，表現(xiàn)為路面松散、麻面、油分流失等。冷再生機(jī)可將磨損老化的表層銑刨掉，再結(jié)合再生技術(shù)，添加新的瀝青結(jié)合料和骨料，使路面恢復(fù)良好的使用性能。相較于傳統(tǒng)的重新鋪設(shè)瀝青面層的方法，冷再生處理方式更加出色，且能減少材料浪費(fèi)，符合可持續(xù)發(fā)展理念。

　　Long term use of asphalt pavement may cause wear and aging on the surface due to factors such as vehicle friction, ultraviolet radiation, and rainwater erosion, resulting in loose pavement, rough surface, and loss of oil flow. The cold recycling machine can mill off the worn and aged surface layer, and then combined with recycling technology, add new asphalt binder and aggregate to restore good performance of the road surface. Compared to the traditional method of re laying asphalt surface layer, cold recycling treatment is more efficient and can reduce material waste, which is in line with the concept of sustainable development.

　　二、水泥混凝土路面的改造

　　2、 Renovation of cement concrete pavement

　?。ㄒ唬┢扑榘逄幚?/p>

　?。?） Broken board processing

　　水泥混凝土路面在長(zhǎng)期使用后，可能因基礎(chǔ)沉降、重載車輛突出等原因出現(xiàn)破碎板現(xiàn)象。冷再生機(jī)可以將破碎的水泥混凝土板進(jìn)行破碎、突出，使其成為顆粒狀的材料。這些破碎后的材料可作為新路面基層的骨料使用，再鋪設(shè)新的面層材料，實(shí)現(xiàn)對(duì)舊水泥混凝土路面的改造。這種處理方式既解決了破碎板帶來的行車安全隱患，又合理利用了廢棄的水泥混凝土材料，減少了建筑垃圾的產(chǎn)生。

　　After long-term use, cement concrete pavement may experience broken slabs due to foundation settlement, heavy vehicle compaction, and other reasons. The cold recycling machine can crush and compact broken cement concrete slabs into granular materials. These crushed materials can be used as aggregates for the new pavement base layer, and then new surface layer materials can be laid to achieve the transformation of the old cement concrete pavement. This processing method not only solves the safety hazards caused by broken boards, but also makes reasonable use of waste cement concrete materials, reducing the generation of construction waste.

　　（2） Road surface structure adjustment

　　當(dāng)需要對(duì)水泥混凝土路面的結(jié)構(gòu)進(jìn)行調(diào)整，如降低路面高度、改變路面基層類型時(shí)，冷再生機(jī)也能發(fā)揮重要作用。它可以快速、出色地對(duì)原有路面進(jìn)行銑刨和破碎，為后續(xù)的路面結(jié)構(gòu)調(diào)整創(chuàng)造條件。例如，在城市道路拓寬改造工程中，利用冷再生機(jī)將原有水泥混凝土路面進(jìn)行處理，以便重新設(shè)計(jì)和鋪設(shè)新的路面結(jié)構(gòu)，滿足交通流量增長(zhǎng)的需求。

　　When it is necessary to adjust the structure of cement concrete pavement, such as reducing the height of the pavement or changing the type of pavement base, the cold recycling machine can also play an important role. It can quickly and efficiently mill and crush the original road surface, creating conditions for subsequent road structure adjustments. For example, in urban road widening and renovation projects, cold recycling machines are used to treat the original cement concrete pavement in order to redesign and lay new pavement structures to meet the demand for increased traffic flow.
