摘要： The object of the present invention is to provide a road surface roughness measuring apparatus for measuring the coefficient of dynamic friction and the roughness of the road surface in each direction at a same section where the coefficient of dynamic friction is measured, said apparatus divides the measuring circle on the road surface into a plurality of sections, on which measuring circle the rotary type unit for measuring the coefficient of dynamic friction measures the coefficient of dynamic friction. The road surface roughness measuring apparatus has: a frame (32) having a plurality of legs (31) used for placing the apparatus on a road surface (G); a rotary shaft (45) mounted on the frame (32) and extending vertically; a rotary encoder (44) mounted on the top end of the rotary shaft (45); a rotation plate (50) mounted on the bottom end of the rotary shaft (45); a motor (39) provided with a speed reducing gear and for driving the rotary shaft via gears (41, 41a); and a laser displacement gauge (51) mounted on the rotation plate (50). The laser displacement gauge (51) is disposed in such a way as to measure a road surface roughness along a measuring circle (P) on which the rotary type unit for measuring the coefficient of dynamic friction measures the coefficient of dynamic friction by the rotation of the rotation plate. The measuring circle (P) is divided into a plurality of sections and the road surface roughness for each section (a to h) is calculated based on the signals of the laser displacement gauge (51) and the rotary encoder (44).
