Description
PVC LINER INTERFACE FRICTION AND SLOPE STABILITY Authors Mr. John Klamut - United States - GAI Consultants, Inc. Mr. Ron Harris - United States - GAI Consultants, Inc. Mr. James Shields - United States - GAI Consultants, Inc. Abstract PVC liners have been used for numerous CCR landfill liner systems. In general, the industry has moved away from the use of PVC liners in favor of HDPE or LLDPE geomembranes. An important reason for this shift is due to the veneer stability of PVC liner systems when compared to HDPE or LLPE geomembrane liner systems. The results of stability analyses and the importance of shear strength testing to evaluate the shear resistance between PVC geomembrane and soil and PVC geomembrane and geosynthetics will be discussed. A summary of interface friction test results using ASTM D5321 will be presented. Current PVC products available on the market and typical results for these products will be presented. Advances in the manufacturing of PVC geomembrane will be presented along with general recommendations for the design of PVC geomembranes in landfill containment systems.
