This book was released on 1990 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of the environmental degradation of geosynthetic materials used in hazardous waste facilities has generated much interest in recent years. Analytical methods are used to supplement conventional structure changes and mechanisms of failure associated with the polymer. Any changes in the base polymer caused by chemical exposure may result in severe changes in strength, durability and serviceability of the geosynthetic. Chemical and physical analytical methods are used in evaluation of chemical compatibility and long-term durability of geosynthetics for several purposes: 1) to verify that geosynthetics tested in advance of landfill construction are essentially the same as those procured for the actual installation, 2) to identify and monitor changes in molecular structure caused by chemical attack, and 3) to provide accelerated assessment of the effects of long-term aging, an especially difficult and as yet, not thoroughly researched topic. These factors can be reviewed by studying the oxidation and solvation properties as well as the change in crystalline structure of the plastics.
