Access Limited was called on to provide emergency rockfall mitigation services at Route 600 Rockslide in Virginia. The event occurred in January 2023 and rock accumulated within the travel lanes of Route 600.
Our skilled rockfall mitigation technicians conducted safety scaling and vegetation removal from the slope and devised a solution utilizing a rope harness system, scaling bars, airbags, and rock mass removal.
The geology at the site is comprised of interbedded shale and limestone of variable thicknesses, highly folded and overturned within the limits of the existing project. The rockfall was controlled primarily by the bedding and joints on the east end of the cut and by differential weathering of the soft units on the west end of the cut. A large overhang and evidence by dilated joints that the existing rock mass mobilized on the east end of the cut.
Rockfall scaling is a common technique used in rockfall mitigation. Learn about this process to reduce the risk of rocks falling onto roads, buildings, or people. It is a technique used to remove loose rocks and boulders from steep slopes or cliff faces to reduce the risk of rockfall.
Rock scaling involves identifying loose rocks and boulders on a slope or cliff face and removing them using manual or mechanical techniques. This process can help to reduce the risk of rockfall by stabilizing the remaining rocks and boulders on the slope or cliff face.
