...J.D. Frost; S.W. Lee This paper summarizes the results of a study that used quantitative measures of surface roughness as the basis for investigating the role of topography on the interface shear mechanism of geomembrane-geotextile interfaces. The results show that the interface strength...

... for a given “smooth” geomembrane surface is principally a function of the relative material hardness, the particle size and angularity, the normal stress, and the soil density. When plowing occurs, the geomembrane surface wears, resulting in altered surface roughness and changed interface strength. This paper...

... landfill liners. The results show that within a 10 mm2 scan area, asperity relief ranges from approximately 0.46 to 2.4 mm. Surface roughness is quantified using mean roughness, root mean square roughness, surface roughness parameter, and fractal dimension. KEYWORDS: Interface strength, Atomic force...
