MIDWEST STATE GAM SURVEY

1. As the asset is defined in the NCHRP

Research Report 903 (Geotechnical Asset Management for Transportation Agencies), does your state inventory:

Embankments
Slopes
Subgrades
Retaining Walls
Landslides (Not an asset in Report 903)
Other (describe here)

MIDWEST STATE GAM SURVEY

2. As the asset is defined in the NCHRP

Research Report 903 (Geotechnical Asset Management for Transportation Agencies), does your state rate:

Embankments

MIDWEST STATE GAM SURVEY

3. If you answered yes to any of the

above, please respond to the following:

Briefly describe how your GAM system came

about

How is it accessed (by the public, internally,

etc.)?

Who populates it?
How do you use the data?
Do you program projects using the data?

MIDWEST STATE GAM SURVEY RESULTS

Inventory:

No states are inventorying

embankments, slopes, and subgrades as specifically defined in Rpt 903

7 of 9 states are either actively

inventorying retaining walls or have development underway with such an inventory “under discussion” in an additional state

MIDWEST STATE GAM SURVEY RESULTS

Inventory:

5 of 9 states are actively inventorying

landslides on either a statewide (2 states) or limited (3 states) basis
