Design and Construction

During conventional paving processes, pavement is constructed with vertical or near-vertical edges. The SafetyEdge℠ instead forms the edge of the pavement into a with a consolidated slope of approximately 30 degrees. This provides a strong, durable transition for vehicles that traverse the pavement edge and helps prevents pavement edge raveling. Research has shown this "transition from on-roadway surface to shoulder and back is so smooth it defies assignment of any degree of severity."

By including the SafetyEdge℠ detail while paving, this safety countermeasure can be implemented system-wide at little to no cost.
