| 摘 要： | 准确的试验数据是路面质量控制的基础,比对试验是保证不同试验数据之间比较的重要途径。根据美国材料与试验协会(ASTM)E691,采用实验室间合作研究来确定试验精密度的方法,对旋转压实仪比对试验方案进行了设计。结合沪宁高速公路扩建工程旋转压实仪比对试验,采用100次旋转压实度比对试验结果,对比对试验评价方法进行了研究,得出稳健统计法比ASTM E691法有更高的灵敏性,更能明确地分析各实验室结果的一致性程度。

| Abstract: | Accurate dada is the basis of quality control in asphalt pavement construction.Comparative-study is used to check different data from different labs in terms of the accuracy of the SGC devices and the operator's skill in the Huning expressway widening project.The experimental design of the SGC comparative study and the analysis results obtained in accordance with ASTM E691"Conducting an Inter-laboratory Study to Determine the Precision of a Test Method" are presented,and different evaluation methods are compared.The results indicate that robust -statistical-method is more sensitive than ASTM E691-method. |
