Vegetation causing gases under geomembrane? Q: I have a site where we are installing a high-density polyethylene (HDPE) liner in an existing pond. Because of some residual heavy metals in the top layer of soil, I would like to strip off the top 3–6 inches (7.6–15.2 cm) of soil and vegetation. Alternatively, we could mow and […]
Yeager Airport: Deconstruction and reconstruction of the side of a mountain
April 1st, 2019
Yeager Airport is located on top of a series of leveled mountains in Charleston, W.Va. Completion of the original airport construction in the 1940s required 9 million cubic yards (6.9 million m3) of soil and rock earthwork (Keller 2017). In 2005, due to Federal Aviation Administration (FAA) safety requirements, it was necessary to construct a […]

The magic of water and geosynthetics
February 1st, 2019
Water is a fundamental issue in many projects using geosynthetics. From erosion control to reservoir liners and covers, from landfill leachate pond barriers to coal ash dewatering, handling water and the effects of water are considerations nearly every engineer employing geosynthetics considers. Geosynthetics can effectively manage water applications of erosion control, reinforcement, barriers, filtration and […]
Modeling demonstrates benefit of geogrid-reinforced aggregate base
December 21st, 2018
Improved modeling of geogrid for use with the Minnesota Department of Transportation’s pavement design software, MnPAVE Flexible, will allow pavement designers to simulate field tests of stiffness and resiliency in pavements over bases with and without geogrid. The department, known as MnDOT, is using modeling results from a recent study to develop a design input that quantifies the […]
