Landslide repairs on US-180 between mileposts 13 and 19, near Luna, Catron County, New Mexico
Three landslides within the Tertiary Pueblo Creek Formation were repaired on US-180 near Luna during 1993 in two separate projects. Data had been initially collected on one of the landslides as far back as 1979. All three had been continuing maintenance problems and regularly received maintenance asphalt patches before being repaired. One of the slide repairs involved excavating material above the slip surface and replacing it with select fill, which was keyed into bedrock for stability. The other two slides were repaired by excavating material above the slip surface and replacing it with local soils and reinforcing geogrid. Both repair methods had sufficiently high safety factors (1.25) when modeled on slope stability computer programs; each method of repair should perform adequately.
