通过对粤赣高速公路沥青比对试验结果进行分析,得出比对试验是判别试验室试验水平高低的有效方法。重点阐述了比对试验的实施方案,数据处理方法,以及如何对数据处理结果进行正确的分析;特别介绍了如何运用2个数据一致性统计量(k值和h值)来判断试验的精密度和准确性,以及试验室数据的误差水平和可靠性。 By analyzing the test results of asphalt in Guangdong-Jiangxi Expressway, it is concluded that the comparison test is an effective way to judge the level of laboratory test. In this section, we focus on the implementation plan of comparison test, the data processing method and how to analyze the data processing results correctly. In particular, we describe how to use two data consistency statistics (k value and h value) to judge the test precision And accuracy, as well as the error level and reliability of laboratory data.
