Medley of Materials Make Debut on Deicing Facility

This article explains the measures taken by the Cleveland Hopkins International Airport to meet 2003 mandates imposed by the Environmental Protection Agency (EPA). The mandate, which dictates rules concerning aircraft deicing, was to be met by October 2006. Specifically, deicing runoff was addressed in that airport's 76-acre deicing facility through a multilayer pavement consisting of a geosynthetic clay, a geoweb polyethylene cellular layer, and an aggregate fill. Geoweb is designed to allow for drainage as opposed to traditional asphalt layers which promote more runoff. Also installed was a 1.6 million gallon capacity tank which collects runoff via gravity. The network of collectors that distribute runoff to this tank covers 11 miles, and will be able to redistribute water depending on its pollution content
