Road surface profiler, road surface profiler performance measuring instrument, and method for assessing performance of same road surface profiler by using same measuring instrument

A road surface profiler performance measuring instrument for implementing a virtual road condition to assess the performance of a road surface profiler (A) including a distance measurement unit (10) and a flatness measurement unit (20), the road surface profiler performance measuring instrument comprising:

• a travelling unit (100) configured to increase moving distance information (a) generated by the distance measurement unit (10);
• a height adjustment unit (200) configured to change height information (b) generated by the flatness measurement unit (20);
• and
• a control unit (300) configured to control the travelling unit (100) and the height adjustment unit (200), wherein
• the distance measurement unit (10) is a circular wheel (11), and the travelling unit (100) comprises:
• a conveyor belt (110) on which the circular wheel is mounted;
• and a rotary drum (120) configured to move the conveyor belt (110),
• the circular wheel (11) comprises:
• a front wheel (11) positioned on the front of the distance measurement unit (10) in a moving direction of the distance measurement unit (10);
• and a rear wheel (12) positioned in rear of the front wheel (11), and the flatness measurement unit (20) comprises an angle measurement sensor (21),
• the angle measurement sensor (21) measures an inclined angle (c) formed by the front wheel (11) and the rear wheel (12), and
• the height adjustment unit (200) comprises a rotating unit (210) configured to change an angle formed by the conveyor (110).
