在济南的道路建设与养护领域，各类先进的路面机械设备如同组建了一支 “超级战队”，各司其职，高效协作，为打造平坦、坚实、耐用的道路立下汗马功劳。这些设备凭借独特优势，成为道路施工不可或缺的 “得力助手”。

　　In the field of road construction and maintenance in Jinan, various advanced road machinery and equipment form a "super team", each performing their own duties and collaborating efficiently, making great contributions to creating flat, solid, and durable roads. These devices, with their unique advantages, have become indispensable "capable assistants" for road construction.

　　摊铺机作为道路铺设的 “先锋大将”，在济南道路建设中扮演着关键角色。其主要任务是将搅拌好的沥青混合料或水泥稳定土等均匀地摊铺在道路基层上。以大型履带式摊铺机为例，它拥有宽大的摊铺宽度，能够一次性完成较宽路面的铺设，极大提高施工效率，减少纵向接缝，保证路面平整度。先进的摊铺机配备高精度的自动找平系统，通过传感器实时感知路面基层的高低变化，自动调整熨平板的高度，哪怕是微小的起伏都能精准应对，使铺设出的路面误差控制在极小范围内，为后续的压实工作奠定良好基础，确保车辆行驶时平稳舒适。

　　As a pioneer in road paving, pavers play a crucial role in the construction of roads in Jinan. Its main task is to evenly spread the mixed asphalt mixture or cement stabilized soil on the road base. Taking a large crawler paver as an example, it has a wide paving width and can complete the laying of wider road surfaces in one go, greatly improving construction efficiency, reducing longitudinal joints, and ensuring road smoothness. The advanced paving machine is equipped with a high-precision automatic leveling system, which senses the real-time changes in the height of the road surface base through sensors, automatically adjusts the height of the ironing board, and can accurately respond to even small undulations, so as to control the errors of the laid road surface within a very small range, laying a good foundation for subsequent compaction work and ensuring smooth and comfortable vehicle driving.

　　压路机紧随摊铺机步伐，堪称道路压实的 “大力士”。在济南，从城市主干道到乡村小道，都能看到压路机忙碌的身影。它通过自身重力或振动产生的作用力，对摊铺后的路面材料进行压实，增强路面结构的密实度和强度。双钢轮压路机适用于沥青路面的初压和复压，其表面光滑的钢轮能有效消除路面的轮迹，使路面更加平整，同时通过振动功能，深入压实沥青混合料，提高路面的稳定性和抗滑性能。轮胎压路机则凭借充气轮胎的弹性，在压实过程中与路面充分接触，产生揉搓作用，进一步提高路面的密实度，尤其适用于压实粘性较大的材料，如沥青混凝土中的细粒式混合料。

　　The road roller closely follows the pace of the paver and can be called the "strongman" of road compaction. In Jinan, you can see the busy figure of road rollers from the city's main roads to rural alleys. It compacts the pavement material after paving through the force generated by its own gravity or vibration, enhancing the compactness and strength of the pavement structure. The double drum roller is suitable for initial and secondary compaction of asphalt pavement. Its smooth surface steel wheels can effectively eliminate the wheel marks on the road surface, making the road surface smoother. At the same time, through vibration function, it deeply compacts the asphalt mixture, improving the stability and anti-skid performance of the road surface. Tire rollers rely on the elasticity of inflatable tires to fully contact the road surface during the compaction process, generating a rubbing effect and further improving the compactness of the road surface. They are particularly suitable for compacting materials with high viscosity, such as fine-grained mixtures in asphalt concrete.

　　铣刨机是道路养护的 “美容师”，主要针对旧路面进行修复作业。当济南的道路出现破损、车辙、拥包等病害时，铣刨机便可大显身手。它利用旋转的铣刨鼓上的刀具，将损坏的路面层铣刨掉，深度可根据实际病害情况精确调节，从几毫米到几十厘米不等。铣刨机作业时，能快速、高效地清除病害部位，为重新铺设新路面提供平整、坚实的基础，不仅提高了道路的平整度和行车舒适性，还能延长道路的使用寿命。而且，铣刨下来的旧料可回收再利用，符合环保理念，降低施工成本。

　　A milling machine is a "beautician" for road maintenance, mainly used for repairing old road surfaces. When the roads in Jinan suffer from damages, ruts, and bumps, milling machines can show off their skills. It uses the cutting tools on the rotating milling drum to mill off the damaged pavement layer, and the depth can be precisely adjusted according to the actual disease situation, ranging from a few millimeters to tens of centimeters. When the milling machine is in operation, it can quickly and efficiently remove the damaged parts, providing a smooth and solid foundation for laying new road surfaces. This not only improves the smoothness and driving comfort of the road, but also extends the service life of the road. Moreover, the milled old materials can be recycled and reused, which conforms to environmental protection concepts and reduces construction costs.

　　冷再生机在济南道路建设中也是一员 “猛将”，它具有独特的环保与经济优势。冷再生机可以在常温下对旧路面材料进行破碎、拌和，并添加适量的水泥、石灰等稳定剂，重新生成可用于道路基层或底基层的材料。这一过程无需将旧路面材料运输至场外处理，也无需大量采购新的建筑材料，大大节省了运输成本和原材料成本。同时，减少了废弃物的排放，降低对环境的影响，实现资源的循环利用。经过冷再生处理的路面基层，与传统施工方法相比，具有良好的整体性和稳定性，能够有效承载路面传来的车辆荷载，为道路的长期使用提供可靠保障。

　　Cold recycling machines are also a strong force in the construction of roads in Jinan, with unique environmental and economic advantages. The cold recycling machine can crush and mix old pavement materials at room temperature, and add appropriate stabilizers such as cement and lime to regenerate materials that can be used for road base or subbase. This process does not require the transportation of old pavement materials for off-site processing, nor does it require the purchase of large quantities of new building materials, greatly saving transportation and raw material costs. At the same time, it reduces the discharge of waste, lowers the impact on the environment, and achieves the recycling of resources. The road base treated with cold recycling has good integrity and stability compared to traditional construction methods, and can effectively bear the vehicle loads transmitted from the road surface, providing reliable guarantee for the long-term use of the road.

　　除了上述主要设备，济南路面施工中还有一些辅助设备同样发挥着重要作用。例如，清扫车负责在施工前后清理路面杂物、灰尘，保持施工场地整洁，为摊铺机、压路机等设备的正常作业创造良好条件；装载机则用于搬运砂石、水泥等建筑材料，其强大的装载能力和灵活的操作性能，确保材料及时供应到施工现场，提高施工效率。

　　In addition to the main equipment mentioned above, there are also some auxiliary equipment that play an important role in Jinan road construction. For example, the sweeper is responsible for cleaning up road debris and dust before and after construction, keeping the construction site clean, and creating favorable conditions for the normal operation of equipment such as pavers and rollers; Loader is used to transport building materials such as sand, gravel, cement, etc. Its powerful loading capacity and flexible operating performance ensure timely supply of materials to the construction site and improve construction efficiency.
