... studies on geomembrane biaxial tensile testing. A double dumbbell-shaped PVC (polyvinyl chloride) GMB specimen was adopted to extend the measurable strain range (Hou et al. 2018 ; Schemmann et al. 2018 ; Zhou et al. 2016). Preliminary tests were conducted and confirmed...

...R.S. McWatters; R.K. Rowe ABSTRACT: The diffusive migration in the aqueous and vapour phases of four volatile organic compounds (VOCs: benzene, toluene, ethylbenzene and xylenes) through samples of 0.76 mm (30 mil) thick flexible poly-vinyl chloride (PVC) and 0.76 mm (30 mil) linear low-density...

...T. D. Stark; H. Choi The objectives of this technical note are to review the gas transport mechanisms through flexible geomembranes, and to measure the methane gas transmission rate, permeance, and permeability coefficient of PVC, LLDPE, and HDPE geomembranes by performing the standard gas...

...T. D. Stark; H. Choi; P. W. Diebel Plasticizers are used to make PVC flexible so it can be used as a geomembrane. Plasticizers can migrate from PVC geomembranes over time because of contact with air, liquid, and/or an absorbent solid material. Plasticizer migration can reduce the flexibility of PVC...

...R.P. Hillman; T.D. Stark Torsional ring shear and large-scale direct shear tests were conducted to investigate the shear behavior of polyvinyl chloride (PVC) geomembrane-geosynthetic interfaces. Specifically, the smooth and faille-finished sides of a 0.75 mm-thick PVC geomembrane were sheared...

... an understanding of the mechanism of water transport through the following different types of geomembranes: high density polyethylene (HDPE), polyvinyl chloride (PVC), and bituminous geomembranes. The use of the hydraulic permeation test and hydraulic conductivity (as defined by Darcy's law) to characterize...

...J.P. Giroud; L.G. Tisinger A relationship between the density of a polyvinyl chloride (PVC) geomembrane and its plasticizer content is established. Approximate linear relationships are proposed, and a numerical application is presented. Equations derived from the density-plasticizer content...

...J.P. Giroud When plasticizer migrates out of a polyvinyl chloride (PVC) geomembrane, the geomembrane shrinks. This paper presents equations that give the changes in volume and dimensions of the geomembrane as a function of the plasticizer content before and after shrinkage. A second series...
