INSPECTION DEVICE OF PAVING GAP AND INSPECTION METHOD OF PAVING GAP

摘要

PROBLEM TO BE SOLVED: To provide an inspection device of a paving gap capable of simply inspecting the paving gap with reliability, and an inspection method of the paving gap.;SOLUTION: The inspection device 1 of the paving gap is constituted of a speaker 11 as a radiation means for radiating pavement with a sonic wave S, a sound pressure measuring instrument 12 comprising a microphone or the like as a sound pressure measuring means for measuring the radiated sonic wave S and the sonic wave S' reflected from the pavement, a particle velocity measuring instrument 13 as a particle velocity measuring means for measuring a particle velocity of the radiated sonic wave S and the sonic wave S' reflected from the pavement, and an information part 4 being an information means for reporting the measured value measured by the sound pressure measuring instrument 12 and the measured value measured by the particle velocity measuring instrument 13.;COPYRIGHT: (C)2007,JPO&INPIT
