走在濟(jì)南的大街小巷，腳下那平整黝黑的路面，承載著車水馬龍的喧囂與行人的腳步，它們大多由瀝青混凝土構(gòu)筑而成。這種材料猶如城市道路的 “黑色黃金鎧甲”，憑借出眾的性能，在濟(jì)南的各類建設(shè)場(chǎng)景中大展身手，成為城市基礎(chǔ)設(shè)施建設(shè)的中堅(jiān)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.

　　在城市主干道建設(shè)中，瀝青混凝土是當(dāng)之無愧的主角。濟(jì)南作為交通樞紐，主干道車流量大，重型車輛往來頻繁，對(duì)路面的耐磨性和抗壓性要求出眾。瀝青混凝土具備良好的彈性與韌性，能夠有效分散車輛行駛產(chǎn)生的荷載，減少路面變形與裂縫的產(chǎn)生。例如經(jīng)十路、濼源大街等城市主干道，采用多層結(jié)構(gòu)的瀝青混凝土鋪設(shè)，底層選用粗粒式瀝青混凝土增強(qiáng)承載能力，上層使用細(xì)粒式瀝青混凝土提高平整度與抗滑性能，既保障了車輛平穩(wěn)通行，又延長了道路使用壽命。同時(shí)，瀝青混凝土路面還具有良好的降噪效果，降低車輛行駛時(shí)產(chǎn)生的噪音，為周邊居民營造安靜的生活環(huán)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.

　　城市次干道與支路同樣離不開瀝青混凝土的應(yīng)用。這些道路雖然車流量相對(duì)較小，但更注重與周邊環(huán)境的結(jié)合及行人的通行體驗(yàn)。瀝青混凝土可以根據(jù)不同區(qū)域的風(fēng)格需求，添加彩色顏料，鋪就色彩豐富的路面。在濟(jì)南的一些特色街區(qū)，如曲水亭街周邊道路，鋪設(shè)紅色或黃色的瀝青混凝土，不僅為街道增添了獨(dú)特的視覺效果，還能起到交通引導(dǎo)的作用，區(qū)分步行區(qū)域與車行區(qū)域。此外，瀝青混凝土施工速度快、養(yǎng)護(hù)周期短，適合在城市內(nèi)部狹窄道路施工，能非常大限度減少對(duì)居民日常生活和交通出行的影響。

　　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.

　　在濟(jì)南的停車場(chǎng)建設(shè)中，瀝青混凝土也發(fā)揮著重要作用。大型商場(chǎng)、寫字樓的停車場(chǎng)，每天車輛進(jìn)出頻繁，容易對(duì)地面造成磨損和破壞。瀝青混凝土停車場(chǎng)地面具有良好的抗磨損性能，能夠承受車輛頻繁的啟動(dòng)、剎車和轉(zhuǎn)彎帶來的摩擦。而且，其表面的粗糙紋理提供了足夠的摩擦力，即使在雨天也能有效防止車輛打滑，保障行車安全。同時(shí)，瀝青混凝土便于修補(bǔ)，當(dāng)停車場(chǎng)局部出現(xiàn)損壞時(shí)，可快速進(jìn)行小面積修復(fù)，恢復(fù)使用功能，降低維護(hù)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.
