摘　　要：通过测定不同温度下的沥青针入度值,按要求对不同温度组合进行针入度指数(PI)计算,结果发现,选取5℃时的PI值不稳定,而选取30℃时的PI值较稳定,并对试验结果进行了讨论。The Penetration Index(PI) of asphalt at different temperatures was calculated according to the requirements of different temperature combinations. The test results showed that the PI value at 5 ℃ was unstable, but the PI value at 30 ℃ was stable, the experimental results are also discussed.

关 键 词：沥青 针入度指数 感温性
