本工作的目的是发展一种新的方法来确定导电沥青混凝土的真实的电阻率的基础上的双电极法。由于接触电阻的影响，测量的电阻率总是不等于真实的电阻率。为了确定真实的电阻率，建立了测量电阻率、接触电阻和真实的电阻率之间的线性关系。然后设计了六个不同石墨含量的试样的实验，并进行了验证配方。实验结果表明，直线的斜率代表接触电阻，截距代表真实的电阻率。揭示了石墨含量对接触电阻和真实的电阻率的影响。结果表明，当石墨含量超过3%时，接触电阻对导电率测量精度的影响更加严重。因此，现在是时候选择这种新的方法来确定沥青混凝土的真实的电阻率，考虑到接触电阻。
The objective of this work is to develop a novel methodology for determining real resistivity of conductive asphalt concrete based on two-electrode method. Due to an influence of contact resistance, the measured resistivity is always not equal to the real resistivity. To determine the real resistivity, a linear relationship of the measured resistivity, contact resistance and the real resistivity was established. Then experiments for six specimens with varying graphite contents were designed and performed to validate the formulation. Results of experiments demonstrate that the slope of the line represents contact resistance, and the intercept indicates the real resistivity. The effects of graphite content on contact resistance and real resistivity are also revealed. Finally, results show that the influence of contact resistance on accuracy of resisitvity measurement becomes more serious if graphite content is beyond 3%. Hence, it is the time to choose this novel methodology to determine the real resistivity of asphalt concrete by taking account of contact resistance.
