PODCAST: Robert Bowers on Geosynthetics in Segmental Concrete Pavements

The Interlocking Concrete Pavement Institute published its Tech Spec 22 this year. The document provides general guidelines on the use of geosynthetics within segmental concrete pavements. ICPI’s Director of Engineering Robert Bowers, P.Eng, spoke to Geosynthetica about the publication and the growing role of interlocking concrete pavement technologies, performance of these systems, sustainability... »

Geosynthetics Education: A Case Study

By Preston Kendall – The International Geosynthetics Society has set a goal of getting geosynthetics engineering information into undergraduate civil engineering programs. This is being accomplished in part through the international Educate the Educators program and the newly created Educate the Students program. The larger task of outreach is certainly ambitious.  The fields of civil and geotechn... »

A Geosynthetic Solution for Tehran Highway Wall

By Maccaferri – For a 33m-high, 300m-long retaining wall along the new Tehran North Highway, a composite geosynthetic solution from Maccaferri is being utilized. This geosynthetic approach has enabled the project team to avoid construction of a bridge or a traditional concrete wall, and in doing so has made the works more cost-effective while simplifying the installation. The ongoing construction ... »

VIDEO: Reduction Factor for Creep Rupture Behavior of Geosynthetics

In HUESKER’s May 2017 videocast, engineer Christoph Hessing discusses a highly important reduction factor that engineers must know to properly design with geosynthetics: creep rupture. This is essential to understanding soil reinforcement. “The purpose of the reduction factors is to take into account the factors influencing product behavior that are likely to be significant in an application,” Hes... »
