HAPI members Tensar International and Corporation and Geotech Solutions, Inc. conducted a Use of Geosynthetics workshop on Oahu (10/18) and Kauai (10/20).
Speakers from Tensars: Lars Nelson, Dennis Rogers, and Garrett Fountain. They gave a presentation on building superior performing HMA pavements and discussed how to get the most use out of Geosynthetics in your asphalt concrete pavements through design and construction.
The workshops included a review of Tensar’s new InterAx geogrid. They also presented their cloud based design software, which can be download at: https://www.tensarplus.com/
Tensar did a demonstration using Geogrid to stabilize a base. Ten tennis balls were stacked in a pyramid; when pressure was applied to the top, the pyramid collapsed. The pyramid was then setup within at wooden triangle, which simulates an individual triangle of the Geogrid. This time when pressure was applied to the top, the pyramid stayed in place.
In addition, Tensar discussed other applications for the use of Geosynthetics such as Construction Platforms, Crane Pads, Drainage Layers and Foundations under Structures.
