제안 방법
- The investigation was carried out in a laboratory using concrete specimens. Concrete specimens with three mixing ratios were prepared and the resistivity measured by the pole electrode method and was analyzed comparatively. Both were conducted with the change in the electrode spacing and age of the concrete.
- In total, 9 concrete specimens were produced with 3 different mix designs with a diameter of 150mm and a height of 300mm, as summarized in Table 2. The resistivity measurements were repeated 5 times using the pole electrode method and the flat electrode method at 7 and 28 days. The results were analyzed by calculating the average value.
- Therefore, this study examined the feasibility of resistivity surveys using a flat electrode method to detect the ground condition under the concrete pavement without damaging the concrete. The survey was carried out in a laboratory using both the pole electrode method and flat electrode method.
- To evaluate the effects of the fine aggregate modulus (S/a) on the resistivity, three concrete specimens were produced for each mix design based on the standard specifications of road construction (ASTM C192/C192M, 2015; MLTMA, 2009). In total, 9 concrete specimens were produced with 3 different mix designs with a diameter of 150mm and a height of 300mm, as summarized in Table 2.

이론/모형
- 5. Table 4 lists the resistivity obtained by subtracting the resistivity obtained using the pole electrode method from that obtained using the flat electrode method. When the resistivity was a positive value, the resistivity obtained using the flat electrode method was larger than that obtained using the pole electrode method.
- Therefore, this study examined the feasibility of resistivity surveys using a flat electrode method to detect the ground condition under the concrete pavement without damaging the concrete. The survey was carried out in a laboratory using both the pole electrode method and flat electrode method. The resistivity of the concrete specimens was measured with respect to the electrode spacing and mixing ratio.
- This study examined the feasibility of a resistivity survey in concrete using flat electrode method. The investigation was carried out in a laboratory using concrete specimens.
- Several electrode array methods are used for resistivity surveying. This study used the dipole-dipole array method, which was performed in the vertical and horizontal directions simultaneously to investigate the two-dimensional structures under the concrete pavement. As shown in Fig.
