PURPOSE:To perform measurement quickly and highly accurately, by providing a traverse between a pair of stands provided at both shoulder parts in the transverse direction of the running road, providing a dial gauge which can be freely moved in the lateral direction in said traverse, and printing the read out values. CONSTITUTION:A pair of the stands 8, which can be implanted upright, are provided at both shoulder parts of the transverse direction of the running road 1, and the traverse 11, which is supported in the transverse direction, is provided between both stands. The dial gauge 21 supports a rotary wheel which can be rotated along the irregularity of the surface of the running road 1 through a spindle 20. The dial gauge 21 is provided on the traverse 11 so that it can be freely moved in the lateral direction. The digital output signal from said dial gauge 21 is inputted into a digital printer 31 through a cable 30. The signal is sampled at every specified lateral distance and printed in the digital printer 31. Thus the irregularity of the surface of the running road 1 can be recorded. |
