Standard Test Method for Determining the Tensile Shear Strength of Prefabricated Bituminous Geomembrane Seams

Importancia y uso:

4.1 The use of PBGM as barrier materials to restrict liquid migration from one location to another in soils has created a need for a standard test method to evaluate the quality of PBGM seams. In the case of PBGMs, it has become evident that seams can exhibit separation in the field under certain conditions. Although this is an index-type test method used for quality assurance and quality control purposes, it is also intended to provide the quality assurance engineer with sufficient seam shear data to evaluate seam quality. Recording and reporting data will allow the quality assurance engineer to take measures necessary to ensure the repair of seams with unacceptable strength during facility construction, and therefore, minimize the potential for seam separation in service.
