GEOWEB 3D system is focus of webinar
July 29th, 2019
Layfield Geosynthetics and Presto Geosystems will host a free webinar, “Basics of Road Design Using Innovative Engineered Technologies,” on Aug. 20, from 10 a.m. to 11 a.m. MDT. Roadway surfaces built over weak subgrades can degrade due to base deterioration that causes deflections, rutting and cracking in the surface layer. The GEOWEB 3D soil confinement […]
Infrastructure funding remains uncertain
April 1st, 2019
Nearly a year has gone by since we published the June/July 2018 issue with a theme of “Geosynthetics Used in Highways and Bridges.” The editorial in that issue noted, “As of this writing, the White House and U.S. Congress are working on an infrastructure bill or bills after President Donald Trump released an infrastructure proposal […]
Tenax presents GRAVEL LOCK, a composite for retaining gravel
March 21st, 2019
Italian company Tenax’s new product GRAVEL LOCK is a geocomposite made up of a cuspated, rolled high-density polyethylene geogrid coupled with a polypropylene nonwoven fabric. It is ideal for creating draining and stable gravel floors for pedestrian and vehicular passage, the shape in rolls and the reduced amount of gravel required for filling (less than […]
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 […]
GMA/IGS-NA to present webinar on geosynthetic-stabilized roads
November 2nd, 2018
The Geosynthetic Materials Association (GMA) and IGS North America (IGS-NA) will sponsor a free webinar entitled “Recent Developments in Geosynthetic-Stabilized Roads: Introduction and Mechanisms,” on Dec. 4, from 1 to 2 p.m. EST. Geotextiles, geogrids and geocells have been used widely in roadway stabilization works throughout the world. In this webinar, Dr. Jie Han will […]
The many applications for geosynthetics in the energy sector
October 1st, 2018
The opportunities for geosynthetics in energy applications are nearly endless. There are huge energy categories, such as oil, natural gas and coal, but geosynthetics also play a role in nuclear energy, hydropower, wind power and solar power, among others. Geosynthetics line storage tanks, support roads to remote sites, line tailings ponds, provide filtration, dewater coal […]
