Damage detection of roads using piezo sensors

You'll need to tell us a bit more.

What sort of piezo electric sensor ?

I know of force, displacement, acceleration, pressure, microphones, acoustic emitters and more.

Why don't you explain what your project is, what you have done so dar and where you are stuck ?

We have taken some readings and waveforms with this piezo sensor on a road using digital oscilloscope....but we don't know how to interpret those readings....our target is to detect how damaged the road is from inside by using these readings we received....we need basically all guidance about instrument, sensor, method....or if we get any good research paper it will be a great help....thank you

Interesting project. There are lots of causes of road damage, but the result is usually a bumpier road. When vehicles go over a bump, their suspension and tires oscillate. You may be able to detect this oscillation and its amplitude with this sensor. It will take some experimentation to get the sensor coupled to the road properly without damaging the road and more experimentation to make sense of the data. You may find some frequencies correlate better to road damage. This is a good application for machine learning, but you probably need multiple installations.

If you are instrumenting the vehicle instead of the road, there are papers on this. I was a reviewer of a Master's thesis on a similar topic a decade ago. It was aimed more at determining when the vehicle would need maintenance, but the instrumentation would be similar.
