2. Survey all state DOTs & identify 5 states for further study
3. Interview DOT staff, local agencies, and industry for input in the 5 example states
4. Conduct detailed phone interviews to obtain specific details

Defining Challenges
![Page 25: Sustainable Infrastructure and Materials · Sustainable Infrastructure and Materials ... •Update to the MEPDG Manual of Practice ... •FAA software - FAARFIELD •Rigid pavement](https://reader031.fdocuments.net/reader031/viewer/2022022513/5aeba7637f8b9ae5318dfb65/html5/thumbnails/25.jpg)
Tools to Address Challenges
State Tools Reported To Address Challenges
Colorado Local agencies are developing fees to address issues with infrastructure damage.
Missouri An approach where the permit fee applied is commensurate with the number of permits issued in order to address funding issues.
Nebraska The cost is being extracted from the corresponding annual budget, as the amount is not significant.
North Dakota The state legislature has provided general fund money from the oil extraction fund to the DOT and local jurisdictions for road and bridge improvements.
Pennsylvania The energy development sector is responsible for the excess maintenance costs, inspection fees, and roadway condition survey costs.
Texas A unique relationship between the current/future energy sectors and railroad commission has been developed. Development of standard lease agreement with an associated fee. Temporary use of water lines (for transporting liquids) in state ROW to reduce roadway truck volumes.

PennDOT Process for Maintaining Roads
![Page 27: Sustainable Infrastructure and Materials · Sustainable Infrastructure and Materials ... •Update to the MEPDG Manual of Practice ... •FAA software - FAARFIELD •Rigid pavement](https://reader031.fdocuments.net/reader031/viewer/2022022513/5aeba7637f8b9ae5318dfb65/html5/thumbnails/27.jpg)
Conclusions • Strong correlation: Increase in damage and
congestion on roads and bridges near energy development activities
• Engineering approaches include: – Increased lane widths & adding paved shoulders – Increasing pavement thickness – Stabilization of unpaved roadway surface layers – Jumper bridges
![Page 28: Sustainable Infrastructure and Materials · Sustainable Infrastructure and Materials ... •Update to the MEPDG Manual of Practice ... •FAA software - FAARFIELD •Rigid pavement](https://reader031.fdocuments.net/reader031/viewer/2022022513/5aeba7637f8b9ae5318dfb65/html5/thumbnails/28.jpg)
Future Research
• Lack of quantitative information being collected • Lack of information on safety and crash statistics,
especially low volume roads • No accurate pavement life predictor nor
estimating damage • Investigation into detour routing • Quantify the extent of damage on more high-type
roadways – Current studies focus on secondary roads in primarily
rural locations
