走在济南的大街小巷，脚下那平整黝黑的路面，承载着车水马龙的喧嚣与行人的脚步，它们大多由沥青混凝土构筑而成。这种材料犹如城市道路的 “黑色黄金铠甲”，凭借出色的性能，在济南的各类建设场景中大展身手，成为城市基础设施建设的中坚力量。

　　Walking through the streets and alleys of Jinan, the flat and dark road beneath my feet carries the hustle and bustle of traffic and the footsteps of pedestrians, mostly constructed of asphalt concrete. This material is like the "black gold armor" of urban roads, and with its excellent performance, it has demonstrated its skills in various construction scenarios in Jinan, becoming the backbone of urban infrastructure construction.

　　在城市主干道建设中，沥青混凝土是当之无愧的主角。济南作为交通枢纽，主干道车流量大，重型车辆往来频繁，对路面的耐磨性和抗压性要求极高。沥青混凝土具备良好的弹性与韧性，能够有效分散车辆行驶产生的荷载，减少路面变形与裂缝的产生。例如经十路、泺源大街等城市主干道，采用多层结构的沥青混凝土铺设，底层选用粗粒式沥青混凝土增强承载能力，上层使用细粒式沥青混凝土提高平整度与抗滑性能，既保障了车辆平稳通行，又延长了道路使用寿命。同时，沥青混凝土路面还具有良好的降噪效果，降低车辆行驶时产生的噪音，为周边居民营造安静的生活环境。

　　Asphalt concrete is undoubtedly the protagonist in the construction of urban main roads. As a transportation hub, Jinan has a high traffic volume on its main roads and frequent heavy vehicle traffic, which requires extremely high wear and pressure resistance of the road surface. Asphalt concrete has good elasticity and toughness, which can effectively disperse the load generated by vehicle driving, reduce road deformation and crack formation. For example, urban main roads such as Jingshi Road and Luoyuan Street are paved with multi-layer asphalt concrete, with the bottom layer using coarse-grained asphalt concrete to enhance bearing capacity, and the upper layer using fine-grained asphalt concrete to improve smoothness and skid resistance. This not only ensures smooth vehicle traffic but also extends the service life of the road. At the same time, asphalt concrete pavement also has a good noise reduction effect, reducing the noise generated by vehicle driving and creating a quiet living environment for surrounding residents.

　　城市次干道与支路同样离不开沥青混凝土的应用。这些道路虽然车流量相对较小，但更注重与周边环境的融合及行人的通行体验。沥青混凝土可以根据不同区域的风格需求，添加彩色颜料，铺就色彩丰富的路面。在济南的一些特色街区，如曲水亭街周边道路，铺设红色或黄色的沥青混凝土，不仅为街道增添了独特的视觉效果，还能起到交通引导的作用，区分步行区域与车行区域。此外，沥青混凝土施工速度快、养护周期短，适合在城市内部狭窄道路施工，能最大限度减少对居民日常生活和交通出行的影响。

　　Both urban secondary roads and branch roads cannot do without the application of asphalt concrete. Although these roads have relatively low traffic volume, they place more emphasis on integration with the surrounding environment and pedestrian experience. Asphalt concrete can add colored pigments according to the style requirements of different areas to pave colorful roads. In some characteristic neighborhoods of Jinan, such as the roads around Qushuiting Street, red or yellow asphalt concrete is laid, which not only adds a unique visual effect to the street, but also plays a role in traffic guidance, distinguishing pedestrian areas from vehicular areas. In addition, asphalt concrete construction is fast and has a short maintenance period, making it suitable for construction on narrow roads within cities and minimizing the impact on residents' daily lives and transportation.

　　在济南的停车场建设中，沥青混凝土也发挥着重要作用。大型商场、写字楼的停车场，每天车辆进出频繁，容易对地面造成磨损和破坏。沥青混凝土停车场地面具有良好的抗磨损性能，能够承受车辆频繁的启动、刹车和转弯带来的摩擦。而且，其表面的粗糙纹理提供了足够的摩擦力，即使在雨天也能有效防止车辆打滑，保障行车安全。同时，沥青混凝土便于修补，当停车场局部出现损坏时，可快速进行小面积修复，恢复使用功能，降低维护成本。

　　Asphalt concrete also plays an important role in the construction of parking lots in Jinan. The parking lots of large shopping malls and office buildings are frequently accessed by vehicles every day, which can easily cause wear and damage to the ground. Asphalt concrete parking lot surfaces have good wear resistance and can withstand the friction caused by frequent starting, braking, and turning of vehicles. Moreover, the rough texture on its surface provides sufficient friction, which can effectively prevent the vehicle from slipping even in rainy weather and ensure driving safety. At the same time, asphalt concrete is easy to repair. When there is partial damage in the parking lot, it can be quickly repaired in small areas to restore its functionality and reduce maintenance costs.
