    In order to solve the pavement-slab breakdowns caused by a poor vibration damping and energy absorption of cement-concrete rigid structures with a lean concrete base, this study proposes an addition ... of a flexible function layer between the lean concrete base and the concrete pavement slab to form a "rigid+flexible+rigid" structure. The conducted experiments use a dynamic signal-testing and analyzing system to collect the frequency signals from the pavement-structure vibration when a small pavement-slab structure is subjected to a ball-drop impact. The results reveal how much vibration is damped out and how much energy is absorbed by adding a flexible function layer. According to the contrastive tests, the pavement-slab vibration is a declining process under an impact load. The vibration damping is more significant with an increase in the thickness of the function layer, but it becomes slower if the layer reaches a certain thickness. The tests also show that a flexible function layer has a significant role in the vibration dampingand energy absorption. Therefore, the cement-concrete pavement structure designed with a flexible function layer can greatly reduce the slab breakdowns caused by the wheel-impact vibrations.
