| 摘要： | This research investigated the impact of MnDOT implementing a w/cm-based specification for concrete pavements. Pavement sections constructed before and after the specification implementation were examined to assess permeability, compressive strength and air-void system parameters. Pavement management system data was examined to identify changes in ride quality associated with the specification change. The results show the change to a w/cm-based specification resulted in concrete with lower permeability, higher strength, and increased air content. The ride quality for those pavements appears to be better and the rate of degradation of ride quality appears to be slower. |
