Utilization of Waste Tires to Reduce Railroad Vibration
This study proposes a means to recycle waste tires as a material to reduce ground vibration. A series of field experiments was carried out to assess the reduction effect of railroad transport vibration by utilizing waste tire chips. The ground vibration during the railroad transport operation was measured in two railroad lines to investigate the vibration characteristics prior to field model tests. Test results showed that the frequency of vibration induced by railroad transport ranged from 5Hz to 100Hz, while the dominant frequency was within the range of 20Hz to 40Hz. A series of field model test was carried out by using tire chips (5cm×5cm in size) as a reduction material for railroad vibration. The field experiment results showed that the reduction effect of waste tires for railroad vibration increased with increasing thickness of the waste tire layer and increasing frequency of the vibration source. From these experimental results, it can be concluded that waste tires can be recycled effectively for reduction of railroad.
