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 concrete pavements of national secondary road. FEM was used to discretize models of different damaged degrees. The influence of different damaged degrees on natural frequencies and modes was studied. It was discovered that the new cement concrete pavement’s frequency was bigger than worn ones, and the modes were influenced by the damage locations and their degrees, the more worn, the more irregular.
