Spent and discarded household fluorescent lamps are recognized as hazardous materials due to their contents of mercury and other pernicious components. The global-wide annual storage and dumping of millions of pieces of this electronic waste result in severe risks to arable land resources and give rise to ecosystem degradation and other environmental problems. A parallel issue is that the imminent depletion of those scarce raw materials used for road construction is now forcing highway administrations to seek sustainable resources. As such, the main purpose of this paper is to explore the feasibility of recycling fluorescent lamps into flexible pavement layers, namely the asphalt wearing and binder course, as an alternative to conventional mineral filler. To this end, a set of laboratory tests were conducted so as to compare and contrast mixtures incorporating recycled florescent lamp with control mixtures. These tests included the Marshall, indirect tensile stiffness modulus, wheel track, indirect tensile fatigue and dynamic creep test. Results demonstrate that the promising performance and cost-effectiveness of incorporating discarded fluorescent lamps into low to moderate traffic road surfaces can provide the pavement industry with new resource options.

废旧的家用荧光灯由于含汞和其他有害成分，因此被认为是危险材料。全球每年数以百万计的这种电子废物的存储和倾倒对耕地资源造成严重的风险，并导致生态系统退化和其他环境问题。一个并行的问题是，用于道路建设的稀缺原材料的即将耗尽，现在迫使高速公路管理部门寻求可持续资源。因此，本文的主要目的是探讨将荧光灯回收到柔性路面层（即沥青磨耗层和粘合剂层）中作为替代常规矿物填料的可行性。为此，进行了一组实验室测试，以比较和对比掺有回收荧光灯的混合物与对照混合物。这些测试包括Marshall，间接拉伸刚度模量，轮距，间接拉伸疲劳和动态蠕变测试。结果表明，将废弃的荧光灯纳入中低交通量的路面具有令人鼓舞的性能和成本效益，可以为路面行业提供新的资源选择。
