PVC GEOCOMPOSITE FOR IMPROVED FRICTION AND PERFORMANCE PROPERTIES

With the emphasis of waste containment being placed upon improving the stability of the various interfaces used in their construction, geocomposites with improved coefficient of friction properties provide possible solutions. The geocomposite addressed in this paper not only offers improved slope stability properties but also other improvevements over geomembranes presently used. In this paper, the geocomposite was compared to a PVC using various index tests. The purpose was to determine what benefits the geocomposite offers over the present practice of placing a geomembrane along with a geotextile in containment applications. The paper also summarizes several case studies in which this geocomposite worked successfully, and some planned futuree commercial uses of this material.
