为规范公路技术状况检测评价工作，提升公路资产管理和养护决策工作的科学化水平，促进我国公路养护高质量发展，通过文献调研，总结并分析了我国现行路面技术状况评价标准与发达国家在指标选取、分项指标权重设置和路况综合评定等方面的差异；通过实地调研与数据分析相结合的方法，探讨了我国目前路面技术状况检测评价工作中存在的主要问题，特别是对我国现行标准中新增的路面磨耗指标进行了重点分析。研究结果显示：①现阶段我国普遍采用的病害采集技术缺少对变形类病害的识别能力，不完全适应现行标准中综合破损率的要求；②路面磨耗指标计算模型所需参数不明确，磨耗评价结果对实际养护工作的指导性不强；③不同路面类型和技术等级的公路采用相同的等级评价标准，难以客观、科学地反映路面使用性能。研究认为，我国路面技术状况检测评价工作中应推广三维检测技术的应用，优化磨耗指标计算模型，完善等级评价标准。
In order to standardize the detection and evaluation of highway conditions, improve the scientific level of highway asset management and maintenance decision-making, and promote the high-quality development of highway maintenance in China, the paper summarized and analyzed the differences of current road condition evaluation standards between China and developed countries in indicator selection, sub-indicator weight setting and comprehensive road condition evaluation; combining field investigation and data analysis, the main problems existing in the current road condition detection and evaluation in China were discussed, especially towards the newly proposed pavement wearing index. This research shows that: ①the distress collection technology commonly used in China at this stage lacks the ability to recognize deformation-type distress and does not fully meet the requirements of the comprehensive distress ratio in the current standards; ②the parameters required for the pavement wearing index calculation model are not clear, and the guidance of wearing evaluation results on actual maintenance is insufficient; ③it is difficult to objectively and scientifically reflect the performance of the pavement using the same grade evaluation standard for different road types and technical grades. The paper argues that the application of three-dimensional detection technology should be further strengthened in the detection and evaluation of road conditions, the calculation model of wearing index should be optimized, and the grade evaluation standards should be improved.
