| 摘 要： | 介绍了沥青针入度指数的由来、计算和误差，PI的分析技巧。用不同温度计算PI值，考察茂名分公司的改性沥青与高等级道路沥青的PI值现状。结果表明：针入度的较小变化引起了PI值的较大变化，增加温度点计算对提高PI的准确度有帮助，但并不能完全满足交通部新标准的要求。

| Abstract: | The stem, calculation,error and analysis of penetration index of asphalt are presented. Using different temperatures to calculate, the penetration index of modified asphalt and petroleum asphalt of Maoming Company were investigated. The research indicates that the prominent changes of penetration index arise from a little change of penetration. The accession of temperature point can improve the accuracy of penetration index, but not completely applicable to the new standard of Ministry of Transportation. |
