农村公路环境友好型沥青路面结构的应用探索

Explore on Application of Environmentally Friendly Asphalt Pavement Structure for Rural Highway

结合南京市浦口区农村公路提档升级工程,以浦合线改造工程为例,在对沥青路面典型结构与病害进行调查分析的基础上,确定了现场水泥冷再生和泡沫沥青厂拌冷再生综合再生的处理方式,同时考虑路面抗车辙的要求,将成品橡胶沥青应用到上面层结构中,通过工程的现场实施及后期观测,表明所采用的路面结构方案是合理、可行的,保证了农村公路的建设质量。

According to rural road upgrade project of Pukou District of Nanjing, taking Puhe line reconstruction project as an example, typical structure and the damage of the asphalt pavement, and confirmed the treatment method of the cement cold regeneration and the cold recycling of the foamed asphalt plant. Considering the requirements of anti-rutting asphalt pavement, factory robber asphalt was applied to upper layer structure. The implementation and post project on-site observation showed that the pavement structure scheme was reasonable and feasible, which could ensure the construction quality of rural highway.
