基于灰色关联度的沥青路面检测数据质量影响因素分析

Analysis of the Factors Influencing the Quality of Asphalt Pavement Inspection Data Based on Gray Correlation

为研究行驶轨迹、车速、设备类型和重复度对沥青路面车辙与平整度检测数据质量的影响,以及行驶轨迹、车速、胎压和水膜加压对抗滑性能检测数据质量的影响,利用灰色关联分析法,通过现场试验和计算定量分析各因素的影响程度,并进行大小排序。研究结果可为提高路面检测数据的质量提供参考。

In order to analyze the influence of factors such as driving trajectory,speed,equipment type,repeatability on the quality of asphalt pavement rutting and evenness inspection data,and factors such as driving trajectory,speed,tire pres⁃sure and water pressurization on the quality of asphalt pavement anti⁃skid inspection data,using the gray correlation analy⁃sis method,through testing on site and calculation,the influence degree of each factor was quantitatively analyzed and ranked.The results can provide reference for improving the quality of pavement inspection data.
