Safety Edge Results
![Page 13: Every Day Countsstatic.tti.tamu.edu/conferences/tsc13/presentations/construction-1/alonzi-obr.pdf• EDC 1 and EDC 2 overview • Safety Edge • High Friction Surface Treatments (](https://reader034.vdocument.in/reader034/viewer/2022042808/5f8740e9b2cd2e225b22e6cf/html5/thumbnails/13.jpg)
What is a High Friction Surface Treatment?
• High Friction Surface Treatments (HFST) are resin-based pavement surfacing overlay systems:
- exceptional skid-resistant properties - retains the higher friction property for a much longer time. • Commercially available • Generally applied in short sections to
improve spot locations where friction demand is critical.
![Page 14: Every Day Countsstatic.tti.tamu.edu/conferences/tsc13/presentations/construction-1/alonzi-obr.pdf• EDC 1 and EDC 2 overview • Safety Edge • High Friction Surface Treatments (](https://reader034.vdocument.in/reader034/viewer/2022042808/5f8740e9b2cd2e225b22e6cf/html5/thumbnails/14.jpg)
HFST Installation
• Manually - Manual mixing of epoxy material and application with squeegee
• Automated (machine-aided) - Machine mixing and application of epoxy (limited hand/squeegee work)
![Page 15: Every Day Countsstatic.tti.tamu.edu/conferences/tsc13/presentations/construction-1/alonzi-obr.pdf• EDC 1 and EDC 2 overview • Safety Edge • High Friction Surface Treatments (](https://reader034.vdocument.in/reader034/viewer/2022042808/5f8740e9b2cd2e225b22e6cf/html5/thumbnails/15.jpg)
Benefits
• Key message: HFST reduce crashes, injuries, and fatalities.
• Benefits include: – customizable to specific state and local safety needs – high return on investment – minimal impact to traffic during construction – negligible environmental impact

What are Intersection & Interchange Geometrics?
• Innovative designs that: – Improve the way traffic makes certain movements – Eliminate, relocate or modify conflict points – Strategically improve signalization
![Page 19: Every Day Countsstatic.tti.tamu.edu/conferences/tsc13/presentations/construction-1/alonzi-obr.pdf• EDC 1 and EDC 2 overview • Safety Edge • High Friction Surface Treatments (](https://reader034.vdocument.in/reader034/viewer/2022042808/5f8740e9b2cd2e225b22e6cf/html5/thumbnails/19.jpg)

• Growing traffic demands • Scarce funding • Restricted ability to add
more lanes or build grade separations
• Need for improved safety for pedestrians, bicyclists and drivers

Why Intersection & Interchange Geometrics?
![Page 20: Every Day Countsstatic.tti.tamu.edu/conferences/tsc13/presentations/construction-1/alonzi-obr.pdf• EDC 1 and EDC 2 overview • Safety Edge • High Friction Surface Treatments (](https://reader034.vdocument.in/reader034/viewer/2022042808/5f8740e9b2cd2e225b22e6cf/html5/thumbnails/20.jpg)
Safety - Fewer conflict points - Encouraging results from early deployments Mobility
- Reduced delay / more capacity Promotes best-value solutions
- Lower ROW & construction costs - Reduced impacts Faster implementation
