| titleOfInvention | Degradation diagnosis device for drainage pavement |
| abstract | (57) [Abstract] [Problem] To efficiently and rationally diagnose deterioration of drainage pavement. SOLUTION: A pavement road surface 25 behind a water supply device 21 is provided. An ultrasonic transmission sensor 22a and an ultrasonic reception sensor 22b are arranged at an interval from each other, and while receiving water from the nozzle 24, the ultrasonic wave transmitted from the transmission sensor 22a is received by the reception sensor 22b. I do. When the drainage is deteriorated, the ultrasonic wave efficiently propagates the water w, When the drainage property is healthy, the ultrasonic wave is attenuated halfway, so that the deterioration state can be determined based on the received signal. |
