Design and Application of a Multichannel Analysis Surface Waves Acquisition System for the Pavement Layers Investigation

This study aims to design and develop a pavement non-destructive quality testing device with the MASW method. Unlike traditional acquisition techniques that plants geophones on pavement, presented approach uses no-tip geophones, placed directly surface preserve its integrity. To proceed, seismograph using an Arduino Due microcontroller connected Raspberry Pi 4 nano-computer was developed. The receivers consist of 6 4.5 Hz GD together by graduated tape control inter-trace distance in order acquire data land-streamer. recording is triggered KY-038 sound sensor. acts as analog-to-digital converter while used real-time visualization processing interface. obtained seismic has been processed Geopsy open-source software which allows analysis inversion dispersion curves. studied system tested different sites. VS VP velocities function depth allowed deduce elastic properties layers decide their mechanical possibility integrating results road banks.
