资源节约环境友好理念在公路大修工程中的实践

Practice of Resource-saving and Environment-friendly Concept in Highway Overhaul

依托G15公路松浦二桥以南大修工程,结合公路自身的病害情况,运用资源节约环境友好的设计理念,设计了利用老路废旧材料及护栏构件的工程技术方案;根据交通特性,应用重载交通改性沥青,有效提高了路面结构上面层的高温稳定性和抗疲劳开裂性能。在获得良好路用性能和经济效益的同时,生态环境效益也非常显著。

Relying on the overhaul project at the south of Songpu Bridge Ⅱ in G15 Highway and combining with the disease situation of the highway,the resource-saving and environment-friendly design concept is used to design an engineering technological scheme using the waste material and guardrail components of old highway.Based on the traffic characteristics,the application of heavy traffic modified asphalt can effectively improve the high-temperature stability and anti-fatigue cracking property of the upper layer of pavement structure.While obtaining the good pavement performance and economic benefits,the eco-environmental benefits are also remarkable.
