给出了沥青体积换算系数与温度相关关系的数学模型，介绍了ＡＴ８９Ｃ２０５１频率数据采集器，进而提出了大粘度沥青流量的模块式智能检测方法。
The mathematic model of the relationship between the volume conversion coefficient and the temperature of asphalt is given. The AT89C2051 frequency data collector is introduced, and then a modular intelligent detection method of large viscosity asphalt flow is proposed.
