传统工艺的传承与优化：济南多数沥青生产企业采用的常规工艺，从原油提炼开始便严格把控。原油经过蒸馏，分离出不同沸点范围的馏分，其中重质馏分进一步加工得到沥青。在这个过程中，对温度、压力等参数的精准控制至关重要。例如，蒸馏温度的细微差异可能导致沥青产品性能的显著变化。

The inheritance and optimization of traditional craftsmanship: Most asphalt production enterprises in Jinan adopt conventional craftsmanship, which is strictly controlled from the beginning of crude oil extraction. Crude oil is distilled to separate fractions with different boiling points, and the heavy fractions are further processed to obtain asphalt. Accurate control of parameters such as temperature and pressure is crucial in this process. For example, slight differences in distillation temperature may lead to significant changes in the performance of asphalt products.

企业通过引进先进的自动化控制系统，实现对生产过程的实时监测与调整，确保每一批次沥青产品质量的稳定性。在沥青拌和环节，将沥青与集料按照精确比例混合，控制好拌和时间与温度，使沥青均匀包裹集料，从而生产出符合道路施工标准的沥青混合料。​

By introducing advanced automation control systems, enterprises can achieve real-time monitoring and adjustment of the production process, ensuring the stability of the quality of each batch of asphalt products. In the asphalt mixing process, asphalt and aggregate are mixed in precise proportions, and the mixing time and temperature are controlled to ensure that the asphalt evenly wraps around the aggregate, thereby producing asphalt mixture that meets road construction standards. ​

创新工艺的探索与实践：部分企业积极探索创新工艺，以提升产品竞争力。比如，一些企业引入了沥青改性技术，通过添加特定的改性剂，如 SBS（苯乙烯 - 丁二烯 - 苯乙烯嵌段共聚物），改变沥青的分子结构，进而改善其性能。

Exploration and Practice of Innovative Processes: Some enterprises actively explore innovative processes to enhance product competitiveness. For example, some companies have introduced asphalt modification technology by adding specific modifiers, such as SBS (styrene butadiene styrene block copolymer), to change the molecular structure of asphalt and improve its performance.

改性后的沥青在高温稳定性、低温抗裂性和抗疲劳性能等方面都有显著提升，能更好地适应济南复杂多变的气候条件以及日益增长的交通流量需求。此外，还有企业在尝试采用更环保的生产工艺，减少生产过程中的能源消耗和污染物排放，朝着绿色生产的方向迈进 。

The modified asphalt has significantly improved high-temperature stability, low-temperature crack resistance, and fatigue resistance, and can better adapt to the complex and changing climate conditions in Jinan and the increasing demand for traffic flow. In addition, some companies are trying to adopt more environmentally friendly production processes, reduce energy consumption and pollutant emissions during the production process, and move towards green production.

道路沥青的主力担当：道路沥青是济南沥青生产的主要产品类型，广泛应用于城市道路、高速公路、桥梁等基础设施建设。其中，重交通道路沥青凭借其良好的粘结性、高温稳定性和耐久性，成为高速公路建设的首选。

The main responsibility of road asphalt: Road asphalt is the main product type of asphalt production in Jinan, widely used in the construction of urban roads, highways, bridges and other infrastructure. Among them, heavy traffic road asphalt has become the preferred choice for highway construction due to its good adhesion, high temperature stability, and durability.

在济南的绕城高速、京台高速济南段等重要交通干道的铺设中，优质的重交通道路沥青为道路提供了坚实的基础，保障车辆在重载、高速行驶条件下，路面不易出现车辙、裂缝等病害，延长了道路的使用寿命。而中、轻交通道路沥青则更多地应用于城市次干道、支路以及小区道路建设，满足不同等级道路的性能要求 。​

In the construction of important transportation arteries such as the Jinan Ring Expressway and the Jinan section of the Beijing Taiwan Expressway, high-quality heavy traffic asphalt provides a solid foundation for the road, ensuring that vehicles are not easily affected by ruts, cracks, and other diseases on the road surface under heavy load and high-speed driving conditions, and extending the service life of the road. Asphalt for medium and light traffic roads is more commonly used in the construction of urban secondary roads, branch roads, and residential roads to meet the performance requirements of different grades of roads. ​

特种沥青的特色应用：除了常规道路沥青，济南的企业还生产一些特种沥青，以满足特定领域的需求。防水沥青在建筑防水工程中发挥着关键作用，无论是屋面防水、地下防水还是桥梁防水，防水沥青以其优异的防水性能和耐候性，有效阻止水分渗透，保护建筑结构不受水的侵蚀。

The characteristic application of special asphalt: In addition to conventional road asphalt, enterprises in Jinan also produce some special asphalt to meet the needs of specific fields. Waterproof asphalt plays a crucial role in building waterproofing engineering, whether it is roof waterproofing, underground waterproofing, or bridge waterproofing. With its excellent waterproof performance and weather resistance, waterproof asphalt effectively prevents water infiltration and protects building structures from water erosion.

在济南众多的商业建筑、住宅小区以及地下综合管廊建设中，防水沥青都得到了广泛应用。此外，还有用于机场跑道建设的机场专用沥青，其对平整度、摩擦系数、抗滑性能等方面有着严格要求，济南的部分企业通过技术攻关，生产出符合机场建设标准的专用沥青，为济南遥墙国际机场等航空枢纽的跑道维护与扩建提供了可靠的材料保障 。​​

Waterproof asphalt has been widely used in the construction of numerous commercial buildings, residential communities, and underground comprehensive pipe galleries in Jinan. In addition, there is airport specific asphalt used for airport runway construction, which has strict requirements for flatness, friction coefficient, anti-skid performance, and other aspects. Some enterprises in Jinan have produced specialized asphalt that meets airport construction standards through technological breakthroughs, providing reliable material support for runway maintenance and expansion of aviation hubs such as Jinan Yaoqiang International Airport. ​​
