摘要
该文概述了沥青针入度、软化点和延度三大指标试验。依据试验数据,总结了试验条件对沥青三大指标试验结果的影响,指出了沥青三大指标试验条件性比较强,试验过程应严格按照规范的要求进行,才能得出准确的试验结果。
The article summarizes three-index test of asphalt needle penetration,softening point and extensibility.Based on the testing data,the article sums up the influence of the testing condition on testing result of three asphalt indexes,and points out that the testing condition performance of three asphalt indexes is stronger,and the testing process should be strictly implemented according to the requirements of the standard.In this way,the correct testing result can be achieved.
