Vibration Analysis on Worn Cement Concrete Pavement

Resonant pavement breaker is an excellent technique to reform worn cement concrete pavement (PCC). When the frequency of the machine adjusted to the resonant frequency of the worn cement concrete pavement, the pavement will be broken to discrete blocks. For the full use of this technique, this article studied the dynamic properties such as natural frequencies and modalities of worn cement ...
