Pavement and Maintenance

The recommended practice of bringing the adjacent soil or aggregate material (unpaved shoulder or modified soil) flush with the top of the pavement often requires frequent maintenance. SafetyEdge℠ eliminates the vertical drop-offs along the pavement edge.

The SafetyEdge℠ improves density at the pavement edge, which makes the pavement more durable. Less frequent road maintenance may be needed as edge raveling is reduced.

• NCAT Evaluates SafetyEdge℠ at Pavement Test Track. This article was published in the January/February 2014 issue of Asphalt Pavement Magazine regarding NCAT's research on improving construction and implementation of SafetyEdge℠.
• Construction of a Safe Pavement Edge: Minimizing the Effects of Shoulder Drop-off. This paper documents the development and construction of the SafetyEdge℠ using two different devices. Findings of this research indicate that the SafetyEdge℠ can be constructed with no impact to production and at less than one percent additional material costs.
• Best Practices for Pavement Edge Maintenance. The objectives for this research were to identify and to effectively communicate best practices for pavement edge maintenance based on institutional knowledge TxDOT Districts.
