摘要： 通过对国内外车辙换算系数取值方法的研究,结合实体工程的实测数据与实际路况的对比,对现有车辙换算系数的优缺点进行了分析,提出了车辙换算系数的连续式计算公式。研究表明:根据现有车辙换算系数计算方法计算得到PCI指标值,与实际路况多数存在较大的偏差;而采用研究提出的车辙换算系数计算公式得到的PCI指标值,与实际路况有较好的一致性。

关键词: 道路工程, 沥青路面路况指数, 连续函数, 车辙换算系数

Abstract: According to the study of the rutting conversion factor calculating method at home and abroad,as well as the measured data of the entity engineering and the comparative analysis of actual traffic on the existing track,the advantages and disadvantages of the current rut deduct value are analyzed.Furthermore,continuous type calculating formula of rut deduct value is proposed.Research shows that: according to the PCI gained by the current track conversion factor,most of the index values have larger deviations than the actual road conditions do;however,the PCI gained through the rut conversion factor formula mentioned above possesses better consistency with actual road conditions.

Key words: road engineering, asphalt pavement condition index (PCI), continuous type calculating formula, rut deduct value
