Anticipated Benefits
Understanding the effects of vibrator design and operation will have the following benefits:
- Optimized vibrator installations leading to reduced costs
- Potential to design mixtures that respond well to vibration thus reducing construction costs
- Prevention of vibrator trails in pavements
- Prevention of honeycomb in structures
- Tighter control of in-place air void systems leading to improved longevity
- Science based guidance for specifiers, inspectors and operators

Vibration is a major element in consolidating concrete pavements through use of the paving machine. There is not a complete understanding of how the vibration affects concrete pavements. With use of the Q MC mixes a better understanding of vibration is critical to improve longevity of concrete pavements in the State of Iowa. I would consider this one of most important research element ever done.
