一种SBS改性沥青施工温度测定方法
摘要：
本发明公开了一种SBS改性沥青施工温度测定方法，属于道路工程领域。该方法包括以下步骤：A、利用旋转粘度计，采用27号转子，在转速100RPM条件下，采集工程实际所用的SBS改性沥青样品在135℃、174℃下的粘度数值；B、绘制粘度对数与温度的关系曲线；C、0.275Pa.s对应的温度为拌合温度，0.55Pa.s对应的温度为碾压温度，插值计算对应的拌合温度和压实温度。与现有设计方法相比，本发明测定方法具有物理意义明确，实验结果准确等特点，具有良好的工程实践效果。
摘要（英）：

The invention discloses a SBS modified asphalt construction temperature determination method and belongs to the field of road engineering. The method comprises the following steps: A, by the utilization of a rotational viscometer, by the adoption of a No. 27 rotor and at the revolving speed of 100 RPM, viscosity number of a SBS modified asphalt sample used in engineering practice is acquired at 135 DEG C and at 174DEG C; B, a relation curve of logarithmic viscosity and temperature is drawn; and C, with the temperature corresponding to 0.275 Pa.s as a mixing temperature and with the temperature corresponding to 0.55 Pa.s as a compaction temperature, corresponding mixing temperature and compaction temperature are calculated by interpolation algorithm. In comparison with existing design methods, the determination method has characteristics of clear physical significance, accurate experimental results and the like, and also has good engineering practice effects.
