SafetyEdge℠ is a simple and effective solution to mitigate pavement edge-related crashes. When installed properly, simply consolidating the edge of the pavement to 30-degree shape during the paving process can eliminate the problem of vertical edge drop-off. Research has shown this shape "provides a transition from on-roadway surface to shoulder and back so smooth it defies assignment of any degree of severity…"
Key benefits of the SafetyEdge℠ technology include:
The SafetyEdge℠ provides a strong, durable transition for vehicles to return to the paved road smoothly and easily. Its shape ensures that tire scrubbing will not occur when the pavement edge is exposed. SafetyEdge℠ can be added to both asphalt and concrete pavement projects.
The graphic below illustrates how a traditional pavement edge compares with the SafetyEdge℠ when newly installed and over time with typical wear and erosion.
FHWA strongly encourages implementation of SafetyEdge℠ given its extreme effectiveness in addressing edge drop-off related roadway departure crashes, simplicity in installation, and low cost. A small investment in training and implementing SafetyEdge℠ has the potential to return great safety benefits.
FHWA brought open houses and demonstration projects to agencies to introduce the purpose and need for the SafetyEdge℠, the practical solution the SafetyEdge℠ provides, the features and benefits, and to answer questions and discuss the advantages of the SafetyEdge℠. Visit the Demonstrations webpage to learn about opportunities and resources.
The brochures and flyer below detail how agencies can implement SafetyEdge℠ and answer common questions related to the treatment.
