摘要
用LVDT式针入度仪可以测定不同荷重、不同温度、不同贯入时间的沥青针入度变化情况,设备简单、操作方便、数据可靠。本文介绍仪器的结构,测定沥青流变参数的方法和对国内外6种沥青的评定结果。
Penetrations of asphalt under different conditions of loading, temperature and penetration time can be measured by LVDT penetration-meter, which is simple in structure and easy to operate giving reliable data. In this paper, the structure of the meter, the method and results of rheological parameters of measurement of six kinds of asphalt are presented.
