摘要
采用ASTM-E691法和稳健统计法对动态模量比对试验结果进行了处理和分析,为了探索试验结果差异性产生的原因,对各实验室成型试件的空隙率进行了分析研究,结果表明空隙率的大小、离散程度直接影响动态模量的试验结果的准确性。
The results of dynamic modulus comparison tests are processed and analyzed by ASTM-E691 and robust statistical method.In order to explore the causes of differences in experiment results,the void ratio of the specimens is analyzed and compared.The results show that the size and dispersion of void ratio directly affect the accuracy of the dynamic modulus test results.
