Short-term questions include the following:

1. Are better construction techniques being employed to ensure better concrete placement and curing? (Tie for first.)

1. What are the effects of abutments? MSE walls? Integral abutments? (Tie for first.)

3. What do different States provide in terms of typical annual maintenance of a bridge? Is it documented? (Tie for third.)

3. What are the various States’ policies/practices on deicing salt application? (Tie for third.)

Long-term questions include the following:

1. What is the role of deck cracking in performance?

2. What is the role of concrete permeability? (Tie for second.)

2. Do the AASHTO designs affect performance, such as requirements for shrinkage and temperature steel? (Tie for second.)

4. Are dynamic response characteristics of structures being captured with the other data? Is there a measurable change in stiffness over time? (Tie for fourth.)

4. What are typical repair schedules, and how do these affect cost and performance? (Tie for fourth.)

6. Are the planning models appropriate for bridge design? Is functional obsolescence more likely than structural deficiency for a 100-year service life?
