WEBINAR: Asperity Height or Asperity Concentration for Geomembranes?

For its next technical webinar presentation, Solmax is asking a unique and important question for geomembranes:  Does asperity height or asperity concentration matter more for increasing interface shear resistance along a geomembrane surface?

Asperity Height Webinar - Solmax - Textured Geomembrane Finish

ASPERITY HEIGHT VS ASPERITY CONCENTRATION

The objective of texturing is to prevent a geomembrane surface from being a critical slip plane that may induce, contribute to, or make worse potential sliding of materials. As a slope angle increases, higher interface shear resistance may be required along the geomembrane interface to prevent contact materials from sliding.

Achieving higher interface shear resistance along a geomembrane surface is sometimes associated with increasing the asperity height from texturing; but, some studies (e.g. Blond and Elie, 2006) have shown that higher asperity heights may not always result in higher interface shear resistance. Asperity height may only matter up to 20 to 25 mils, beyond which no further gains may be achieved in interface shear resistance (Blond and Elie, 2006).

So, if asperity height has a limit for increasing interface shear resistance, how else can interface shear resistance be increased with textured geomembranes? Will increasing the concentration of asperity and not the height help?

This free November 28 webinar (registration required) will review Blond and Elie’s findings for asperity height vs. interface shear resistance, and evaluate the contribution of asperity concentration to interface shear resistance relative to asperity height.

Registration is first come, first served. A limited number of spots are available.

The company invites participants to contact its team after the webinar if PDH credits are desired.

OTHER SOLMAX TECHNICAL WEBINARS

The asperity height vs. asperity concentration technical webinar continues the company’s run of high-quality webinar offerings on important geomembrane design and performance topics. Earlier this year, for example, it presented a session on geomembrane wrinkle management.

Other high profile webinars from the company include Enhancing Quality Assurance with Conductive Geomembranes and Flat Die and Blown Film Geomembranes.
