| description | PROBLEM TO BE SOLVED: To measure the clogged state of pavement accurately in a short time by observing the current flowing between a pair of electrodes arranged on a road to be measured as a function of the time. SOLUTION: A pair of electrodes 11 , 12 are arranged on a road and the current flowing between the electrodes 11 , 12 is measured at a measuring section 3 as a function of the time and recorded. A plurality of models corresponding to different clogging states are previously held at the measuring section 3 and the recorded current values are compared with the models to determine the clogging state of the road which is then presented at a display section 2. Installation interval of the electrodes 11 , 12 is set at 30-50 cm and about 100 cc of brine is employed as an electrolyte. The electrolyte is poured from a tunnel section 4 and absorbed by a water absorbing layer 10. The electrolyte is absorbed, as it is, into the ground when a clogging layer 20 is not clogged and the electric resistance between the electrodes 11 , 12 is sustained at a high level for a long time as compared with the case where the clogging layer 20 is clogged. According to the method, clogging of the clogging layer 20 can be measured accurately in a short time. |
