Road markings, such as lane dividers and pedestrian crossings, are integral in ensuring the safety of road users. However, traditional markings frequently exhibit limitations, including short lifespans, diminished visibility, and significant maintenance costs, particularly as traffic volumes increase. To address these persistent challenges, this study presents a thermoplastic road marking system that combines material innovation and advanced application techniques. Central to this approach is the portable heating system, equipped with ceramic heaters and precise temperature controls, which facilitates uniform heating while mitigating fire risks. The thermoplastic blend, processed into pre-formed sheets, was integrated with this heating technology. Together, these components enabled a two-phase process, engraving asphalt surfaces followed by sheet integration, that ensured robust adhesion and seamless bonding. Field trials conducted on various asphalt types validated the system's reliability, demonstrating its durability under traffic loads and consistent visibility. By integrating durable materials with advanced application methods, this methodology significantly enhances the efficiency, longevity, and safety of road markings. It presents a practical and scalable solution for modern infrastructure needs. Future research will focus on evaluating the system's long-term performance under extreme weather conditions to further optimize its applicability.
道路标线，如车道分隔线和人行横道，对于确保道路使用者的安全至关重要。然而，传统标线常常存在局限性，包括使用寿命短、能见度降低以及维护成本高昂，尤其是随着交通流量增加时。为应对这些长期存在的挑战，本研究提出了一种热塑性道路标线系统，该系统结合了材料创新和先进的应用技术。这种方法的核心是便携式加热系统，配备陶瓷加热器和精确的温度控制，既能促进均匀加热，又能降低火灾风险。加工成预制板材的热塑性混合物与这种加热技术相结合。这些组件共同实现了一个两阶段过程，即先在沥青表面雕刻，然后进行板材整合，确保了牢固的附着力和无缝粘结。在各种沥青类型上进行的现场试验验证了该系统的可靠性，证明了其在交通荷载下的耐久性和一致的能见度。通过将耐用材料与先进的应用方法相结合，这种方法显著提高了道路标线的效率、使用寿命和安全性。它为现代基础设施需求提供了一个实用且可扩展的解决方案。未来的研究将集中在评估该系统在极端天气条件下的长期性能，以进一步优化其适用性。
