| 摘 要： | 在分析现有沥青感温性指标的基础上，讨论了针入度指数的局限性，认为采用粘温指数VTS]能够合理表征沥青在路面服务温度内的感温性。并建立了针入度和粘度的换算关系，通过3种沥青实例计算了其VTS]，再分析了计算模型的局限性和改性措施。结果表明，通过采用动态剪切流变仪或针入度试验结果换算出沥青粘度，来求算VTS]是可行的。

| Abstract: | Based on the discussion of the existing asphalt temperature susceptibilities, the limitations of Penetration Index PI] were discussed and the Viscosity-Temperature Susceptibility VTS] was shown to be suitable to describe the asphalt temperature susceptibility of the service pavement temperature span. Then the relationship between penetration and viscosity was set up. According to the test results of three kinds of asphalts, their VTS] were exemplified, and the computing model limitation and its improvement were analyzed. The results show that it is reasonable to get the VTS] with the DSR and penetration test results. 2 tabs, 2 figs, 7 refs. |
