GEOTrac Rapide is working on test method to evaluate impressions on test surface from cylinder test

GEOTrac Rapide is working on a test method to evaluate all of the impressions on test surface from the cylinder test, in order to avoid subjectivity in visually identifying the three deepest impressions for measurement. Russ Tebay also has equipment to measure the hydraulic conductivity of GCLs under a confining pressure and high water pressures.
