[0023] During testing, the sample is placed on the sample placing seat 2, and the sample bottom is stabilized by the sample bottom fixed cylinder 3. Then, the multiple lift columns 4 are evenly raised around the sample placing seat 2 on the test platform 1, and the pressure applying mechanisms 5 installed on these lift columns 4 are aligned with the center line of the sample. By applying vertical pressure to the sample through the pressure applying mechanisms 5, the stress condition in actual road use is simulated, so as to evaluate the strength performance of the sample.
