路面機械是用于公路、城市道路、機場道面等工程施工的專用工程機械，涵蓋從路基處理到路面成型的全系列設(shè)備。一條高質(zhì)量的現(xiàn)代化公路，從荒蕪的土地到平整的黑色路面，背后是一支由數(shù)十種機械設(shè)備組成的“筑路軍團”協(xié)同作戰(zhàn)的結(jié)果。

Road surface machinery is a specialized engineering machinery used for the construction of highways, urban roads, airport pavements, and other projects, covering a full range of equipment from roadbed treatment to pavement shaping. A high-quality modern highway, from barren land to smooth black road surface, is the result of the coordinated operation of a "road construction army" composed of dozens of mechanical equipment.

路面機械的完整分類體系體現(xiàn)了道路施工的工序邏輯。根據(jù)路面結(jié)構(gòu)層和機械用途，路面機械可分為四大類：面層施工機械、基層施工機械、瀝青材料加工處理設(shè)備和石材集料加工處理設(shè)備。具體到瀝青混凝土路面的施工，完整的設(shè)備鏈條包括：瀝青儲存與加熱設(shè)備、瀝青噴灑機、瀝青混凝土攪拌設(shè)備、瀝青混凝土攤鋪機、石屑撒布機以及各類壓實機械。每一類設(shè)備都在特定的施工環(huán)節(jié)中發(fā)揮著不可替代的作用。

The complete classification system of road machinery reflects the process logic of road construction. According to the pavement structure layer and mechanical use, pavement machinery can be divided into four categories: surface construction machinery, base construction machinery, asphalt material processing equipment, and stone aggregate processing equipment. Specifically for the construction of asphalt concrete pavement, the complete equipment chain includes: asphalt storage and heating equipment, asphalt sprayer, asphalt concrete mixing equipment, asphalt concrete paver, stone chip spreader, and various compaction machinery. Each type of equipment plays an irreplaceable role in specific construction processes.

攤鋪機是路面機械中的“核心將領(lǐng)”。攤鋪機主要用于高等級公路基層和面層各種材料的攤鋪作業(yè)，由行走系統(tǒng)、液壓系統(tǒng)、輸分料系統(tǒng)等多個系統(tǒng)協(xié)同配合完成工作。它的核心任務(wù)是將瀝青混合料均勻地攤鋪在路基或路面基層上，并進行整形和初步振實?，F(xiàn)代攤鋪機的工作寬度覆蓋4.5米至12.5米不等，能夠滿足不同項目規(guī)模的施工要求。先進的攤鋪機配備智能找平系統(tǒng)，可實現(xiàn)毫米級的攤鋪精度控制。攤鋪機建議與瀝青混凝土攪拌設(shè)備配套使用——攪拌設(shè)備生產(chǎn)出合格的混合料，攤鋪機將其轉(zhuǎn)化為平整的路面層。

The paver is the "core leader" in road machinery. The paver is mainly used for paving various materials on the base and surface layers of high-grade highways, and is completed by multiple systems such as the walking system, hydraulic system, and material distribution system working together. Its core task is to evenly spread asphalt mixture on the roadbed or pavement base, and carry out shaping and preliminary compaction. The working width of modern pavers ranges from 4.5 meters to 12.5 meters, which can meet the construction requirements of different project scales. The advanced paver is equipped with an intelligent leveling system, which can achieve millimeter level paving accuracy control. The paver must be used in conjunction with asphalt concrete mixing equipment - the mixing equipment produces qualified mixture, which is then converted into a smooth pavement layer by the paver.

壓路機是路面機械中的“壓實主力”。壓路機以機械本身的重力作用，對路基、穩(wěn)定土及瀝青混凝土路面層進行壓實作業(yè)。壓實方式可分為滾壓、振實和夯實三種，對應(yīng)的設(shè)備分別為靜壓壓路機、振動壓路機和振動平板夯。壓路機廣泛用于高等級公路、鐵路、機場跑道、大壩、體育場等大型工程項目的填方壓實作業(yè)。在瀝青路面施工中，壓路機需要按照初壓、復(fù)壓、終壓的順序進行作業(yè)——初壓用靜壓使混合料穩(wěn)定，復(fù)壓用振動突出達到設(shè)計壓實度，終壓用靜壓消除輪跡。不同噸位和類型的壓路機相互配合，才能保證路面達到設(shè)計要求的密實度和平整度。

The road roller is the "main compaction force" in road machinery. The roller compacts the roadbed, stabilized soil, and asphalt concrete pavement layer by the gravity of the machinery itself. The compaction methods can be divided into three types: rolling, vibrating, and compacting, with corresponding equipment being static pressure rollers, vibrating rollers, and vibrating plate compactors. Rollers are widely used for filling and compaction operations in large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and sports stadiums. In asphalt pavement construction, the roller needs to operate in the order of initial compaction, secondary compaction, and final compaction - static pressure is used for initial compaction to stabilize the mixture, vibration compaction is used for secondary compaction to achieve the designed compaction degree, and static pressure is used for final compaction to eliminate wheel marks. The coordination of rollers of different tonnages and types is necessary to ensure that the road surface meets the design requirements for compactness and smoothness.

路面銑刨機是路面養(yǎng)護維修中的“外科醫(yī)生”。銑刨機主要用于瀝青混凝土路面的開挖翻新，也可用于清除路面擁包、油浪、網(wǎng)紋、車轍等缺陷，還可開挖路面坑槽及溝槽。在舊路改造和路面大修工程中，銑刨機先將破損的舊路面層銑削清除，為重新攤鋪創(chuàng)造條件。

Road milling machine is the "surgeon" in road maintenance and repair. The milling machine is mainly used for excavation and renovation of asphalt concrete pavement, and can also be used to remove defects such as road bumps, oil waves, mesh patterns, and ruts. It can also excavate road pits and grooves. In the renovation and major repair of old roads, milling machines first remove the damaged old pavement layers by milling, creating conditions for re paving.

路面機械的發(fā)展趨勢正朝著智能化、自動化和綠色化方向快速演進?，F(xiàn)代路面機械普遍采用液壓傳動技術(shù)、電子控制技術(shù)，實現(xiàn)機電液相結(jié)合。激光、超聲波等非接觸傳感技術(shù)和計算機技術(shù)的應(yīng)用，使操作更加省力、合理。5G遠程操控、AI攤鋪控制、無人駕駛壓路機集群等技術(shù)已逐步在工程項目中得到應(yīng)用。與此同時，電動化、氫能動力系統(tǒng)等新能源技術(shù)也在推動路面機械向綠色低碳轉(zhuǎn)型。路面機械的發(fā)展與路面施工新技術(shù)、新工藝、新材料的發(fā)展密切相關(guān)，兩者相輔相成，共同推動著道路建設(shè)行業(yè)的技術(shù)進步。

The development trend of road machinery is rapidly evolving towards intelligence, automation, and greening. Modern road machinery generally adopts hydraulic transmission technology and electronic control technology to achieve electromechanical hydraulic integration. The application of non-contact sensing technologies such as laser and ultrasound, as well as computer technology, makes operations more effortless and precise. Technologies such as 5G remote control, AI paving control, and unmanned road roller clusters have gradually been applied in engineering projects. At the same time, new energy technologies such as electrification and hydrogen power systems are also driving the transformation of road machinery towards green and low-carbon. The development of road machinery is closely related to the development of new technologies, processes, and materials for road construction. The two complement each other and jointly promote the technological progress of the road construction industry.
