| 摘要： | Asphalt concrete moisture damage is a widespread problem with distress mechanisms capable of stemming from multiple sources including materials selected, stockpile moisture contents, plant production, construction, and sustained elevated moisture levels under heavy traffic. Rapid deterioration of pavements occurs due to moisture damage, yet many key aspects of the problem are not fully understood and some of the behaviors that are better understood are not always monitored or controlled. Moisture damage practices vary between the auspices of different agencies. To provide a forum to improve resistance of asphalt concrete to moisture damage, a half-day workshop was held at the 91st Annual Meeting of the Transportation Research Board in 2012. The workshop was organized to provide a global assessment of moisture damage from materials and construction through service. Test methods and theoretical aspects of moisture in relation to asphalt concrete were also considered. The workshop provided best practices, but also provided forums to discuss areas where improvement is needed. |
