Core Viewpoint - The successful application of "Kunlun·Huanxiling" asphalt in the renovation of Chang'an Avenue demonstrates the technological strength and brand commitment of China National Petroleum Corporation (CNPC) through the use of 100% domestically produced high-end asphalt products [1][2]. Group 1: Product Performance - "Kunlun·Huanxiling" asphalt features five outstanding characteristics: non-sticky wheels, high load resistance, rutting resistance, aging resistance, and odorless properties, which enhance construction efficiency and ensure long-term stability under heavy traffic and temperature variations [2]. - The product's excellent aging resistance extends the lifespan of the pavement, while its environmentally friendly nature ensures comfort for construction sites and surrounding areas [2]. Group 2: Research and Development - The development of "Kunlun·Huanxiling" asphalt involved a multi-year, interdisciplinary collaborative research effort, addressing technical challenges related to the stable dispersion of high proportions of SBS modifiers in traditional low-grade asphalt [1][2]. - The research team proposed the "composite modification of elastomers" theory, leading to the successful development of high-viscosity and high-elasticity modified asphalt, achieving domestic substitution [1]. Group 3: Implementation and Logistics - CNPC's comprehensive approach includes efficient coordination among various units, ensuring timely completion of the project within a limited night construction window [1][3]. - The logistics support system, including dedicated pipelines for raw material transportation and a specialized logistics line for Chang'an Avenue, has been established to ensure high-quality application of the asphalt on-site [3]. Group 4: Strategic Importance - The successful implementation of "Kunlun·Huanxiling" asphalt aligns with China's innovation-driven development strategy, showcasing CNPC's commitment to tackling key core technologies and promoting material localization [2]. - The company aims to continue demonstrating its innovative achievements and responsibility in the high-end materials sector through ongoing projects using "Kunlun" brand asphalt [3].

在项目方技术团队实地考察期间，辽河石化展示了全流程工艺保障体系：从基质沥青优选、SBS改性剂 配比到生产参数调控，结合抗变形、抗老化等专项检测体系及三级质控流程，确保产品适配严苛标准。 最终，辽河石化提交的第三批次样品实现关键性能突破——软化点稳定达到80℃以上，老化后5℃延展 性提升至29cm，较同类产品提高31.8%。 中化新网讯 近日，辽河石化公司"昆仑·欢喜岭"沥青首次应用于一汽-大众汽车试验场改扩建项目，实现 国内高端汽车试验场沥青国产化的重大突破。 为攻克这一项目，辽河石化技术团队针对试验场核心需求，通过反复样品测试和配方优化精准匹配技术 指标，销售部门则充分发挥协调作用，全力推动合作进程，积极促成项目落地。 据悉，一汽-大众汽车试验场作为国内规模最大、技术最先进的汽车综合测试基地，需模拟全球极端工 况：-40℃极寒至60℃高温的剧烈温差、单轮12吨荷载的持续碾压，以及日均超300次的重载弯道测试。 这些条件对路面沥青提出了严苛要求——既要在高温下抵抗车辙变形，又要在低温环境中保持抗裂韧 性，还要具备超强抗疲劳性能以应对高频冲击。 ...
