Geocomposite lamination strength ASTM test method: Time for an update

August 1st, 2018

Recent project experience that included continuous peel testing across the roll width of geocomposite materials has shed light on the issue of peel strength between geotextiles and geonets that are heat-bonded together. The variability of peel strength across a roll width is found to be much greater than expected, with the typical standard deviation often […]

Springtime failure of a cold-climate geotextile riprap slope

June 1st, 2018

Geotextiles play an essential role in geotechnical projects. A significant use for geotextiles is as a separator and filter in drainage and erosion control applications (Holtz 2002). A temporary erosion control application geotextile, such as silt fencing, is used to prevent soil erosion by containing the soil and turbid water in a onetime operation. For […]
