Erosion and Sediment Control

Product Case Study

Atlanta Airport 5th Runway Slope Stabilization

Monday, February 12
2:50 PM - 3:50 PM

PDH: 1

Location: 103B

The Hartsfield–Jackson Atlanta International Airport is the worlds busiest airport, accommodating over 100 flights per hour. In 2016, the slope adjacent to the 5th runway had experienced surficial slope failure after a prolonged rain event and was in need of repair. After considering various traditional solutions, the airport chose to use ARMORMAX 75 to provide an engineered earth armoring solution to stabilize against geotechnical instability and erosion. This presentation will discuss the design approach, installation procedure, and proven success of ARMORMAX 75 in slope stability applications.
