摘　　要：跟踪检测调查路段9年内泡沫沥青冷再生路面损坏PCI、路面车辙RDI、道路平整度RQI、路面结构强度PSSI,分析在役泡沫沥青冷再生路面服役期间技术状况衰减规律。结果表明:服役9年,在承受4928万次标准轴载累计当量轴次后,泡沫沥青冷再生路面的PCI、RDI、RQI、PSSI均评定为优,服役期间泡沫沥青冷再生路面结构弯沉几乎没有衰减,路面未产生结构性车辙,轮迹处车辙深度小于10 mm,泡沫沥青冷再生路面具有优异的使用性能与良好的服务水平,符合长寿命沥青路面特征。The PCI,RDI,RQI and PSSI of the cold recycled foam asphalt pavement during the investigation section in 9 years were tracked and detected,and the attenuation law of the technical condition of the cold recycled foam asphalt pavement during service was analyzed.The results showed that after 9 years of service and 49.28 million cumulative equivalent axis loads of standard axle load,PCI,RQI,RDI and PSSI of foam asphalt cold recycled asphalt pavement were rated as excellent.During the service period,the structural bending of foam asphalt cold recycled pavement almost did not attenuate,no structural ruts were produced on the pavement,and the rut depth at the wheel track was less than 10 mm.The cold recycled foam asphalt pavement has excellent performance and good service level,which accords with the characteristics of long-life asphalt pavement.
