Effects of Flexible Functional Layer Incorporated with Rubber Powder on the Vibration Reduction of Cement Concrete Pavement

Article Preview

Abstract:

Small sized specimen of cement concrete pavement structure was prepared indoors. By utilizing the dynamic signal tester and obtaining the vibration frequency domain signals through the falling-ball vibration impact test method, the attenuation rules of the vibration response of the pavement structure were analyzed and the effects of the flexible functional layer on the vibration-reduction and energy-absorption were studied. The results showed that, after compared with the normal flexible functional layer, the flexible functional layer incorporated with rubber powder resulted in the pavement structure having the better capacities of vibration-reduction energy-absorption and impact resistance. Accordingly, the rupture failure of the cement concrete pavement induced by vehicle load can be reduced.
