Description:
The overall objective of this project was to provide a technological base for determining the chemical resistance and long-term durability of geotextiles, geonet and pipe with waste solutions representative of those to which the products might be exposed in a waste containment facility. xperiments were performed to evaluate proposed testing procedures based on EPA Method 9090 with modifications to accommodate geotextiles, geonets and pipe. nalytical techniques standard to the chemical sciences were employed to study chemical degradation of selected geosynthetics. hese results were compared to physical property data. elt index, Method E of polypropylene geotextile was an effective index test. or PET geotextile, grab strength and permittivity yielded useful data. longation at break was found to be an acceptable index test for high density polyethylene geonet. dditionally, it was concluded that further work was needed for establishing index tests for pipe products. ourier transform infrared spectroscopy (FTIR) was applied and found to require expertise in sample preparation and interpretation since accepted evaluation criteria are lacking. hermal methods provided a limited amount of useful data. inally, it was concluded that although chemical analyses provide precise data, not all available methods are applicable to all materials.
