I posted about the 10th anniversary of the Christchurch Earthquake, but there was another notable earthquake anniversary recently…the 50th anniversary of the 1971 San Fernando earthquake. Khaled Chowdhury from the US Army Corps of Engineers […]
GeoSynthetica was kind enough to track down an interesting case study in the use of geosynthetics at a new de-icing facility at Cleveland’s Hopkins International Airport. Ethylene Glycol and Propylene Glycol are commonly used de-icing chemicals. Most de-icing is done at the gate to avoid flight delays, but it also increases the chance of environmental contamination. In the design of a new dedicated de-icing facility at the airport, geosynthetic clay liners (GCL), Geocells, geotextiles and geocomposites were all used to handle chemical-laden runoff as well as regular runoff during the non-icy times of year. Also there is a problem with high water table and a resulting detrimental effect on the pavement subgrade. This is where the aggregate-filled geocells were used. Read on for the link.
