摘　　要：路面状况检测是公路部门要进行的一项常规性工作,其对路面使用性能评价、预测模型的构建和养护措施的制定等都具有十分重要的意义。根据抽样检验理论,同时结合路面使用性能指标特点研究了不同抽样方案对养护路段划分的影响。结果表明:路面使用状况检测数据的变异性、小样本抽样方法均会造成路段划分失误,甚至会出现路面状况差的路段不能够被发现,而路况好的路段却被判定为需要维修路段的情况。其结果可为路面养护决策及相关技术规范的修订提供参考。Pavement condition detection is a routine work to be carried out road sector. It is important to evaluate pavement performance and built prediction models and choose road maintenance programs. Based on sampling theory,this paper studied the effects of different sampling plans on maintenance sections of pavement performance characteristics. The results showed that： variability,small sample surface sampling method to detect data usage will cause sections divided mistakes,poor road conditions may even not be found,and a good section of the road but was determined to be in need of repair sections of the case. This result can provide reference for pavement maintenance decision and related amendments to the technical specifications.
