From page 44...
... The purpose of this questionnaire is to solicit input on best practices for minimizing damage of asphalt and composite pavements due to the presence of water. The survey results will help to identify specific pavement features and practices used successfully by agency personnel, and to identify agencies that have employed unique or innovative practices with high potential for success.
