摘要

Vibratory rollers are used to dynamically compact asphalt or bituminous layers of more than 100 mm thickness. The paper deals with the question whether or not such machinery should be allowed to compact pavement on a bridge deck. As no experimental or analytical data related to this problem could be found tests were performed on a reinforced concrete bridge exhibiting a 5 Hz fundamental natural frequency. Two types of vibratory rollers with forcing frequencies in the 35...70 Hz range were used to compact the pavement and the resulting bridge vibrations were monitored. The bridge vibration velocity was smaller than 15 mm/s for both rollers. No sign of resonance between the rollers and the bridge superstructure was to be observed. Therefore, no reason could be found to ban vibratory rollers from compacting pavement on bridges.
