1224 - Roadside repairs

Tuesday, January 26 2:30 PM- 4:00 PM ET
Scott Lucas, Ohio Department of Transportation
Sponsored by:
Standing Committee on Roadside Maintenance Operations (AKR20)

The poster session contains two papers related to roadside issues.  The first paper covers roadside slope failures. As part of a broader study on roadside slope repair measures, the paper intended to identify “complementary” slope repair measures and their recommended practices to sidestep recurring failures. The findings of this study show that the application of simple slope repair methods can reduce roadside slope failures and save tax payer dollars.  The second paper involves LiDAR to mapping the profile of the roadside ditch.   Error propagation models and previous field test suggest this technology can map the vertical profile of a ditch with an accuracy of 2-3 centimeters at distances up to 30 meters from the mobile mapping vehicle.
