Two new standards from the Geosynthetics committee of ASTM will help define properties that can be used in the design of geosynthetic reinforced pavement. I know in my practice in Arizona, ADOT simply allows a boost of Resilient Modulus (R-Value) of 10 when biaxial geogrids are used. Perhaps in time this will lead to a design method to account for the geosynthetic reinforcement in a more analytical way. [Source: Geosynthetics Magazine]

The estimated society cost of landslides in the U.S. is estimated at $2-5B and worldwide might even approach $10B. The percentage triggered by surface erosion is certainly a major contributor. While the mechanisms of soil […]
