THE PERFORMANCE of Tensar’s new TriAxTM geogrid has received a major endorsement from Geosynthetics professionals in China on the eve of its launch in the country.
Chinese Technical Association on Geosynthetics (CTAG) and the Chinese Chapter of the International Geosynthetics Society (CCIGS) presented an innovation award to Tensar International on 20th March 2009 at a specially arranged seminar in Wuhan.
The seminar heard how ongoing research and trials by several different Chinese universities and institutions are confirming that Tensar geogrids, including TriAx™ outperformed other biaxial geogrids tested. TriAx has recently been launched in China and is expected to make a major contribution to sustainable civil engineering projects in China.
The revolutionary new TriAx™ geogrid was launched in the UK and Europe in 2007. TriAx™ is being shown to offer superior performance in multi-directional stiffness and aggregate confinement, which enables better radial load resistance, resulting in aggregate base thickness and improved resistance to rutting.
The results of trialling in China were presented to major engineering consultants and academics from across China who attended the seminar, and included conclusions that in-ground performance testing is the key to understanding geogrid performance and not relying on the simple measure of tensile strength (Professor Yang, Chonquing Transportation University, trafficking trials).
This was endorsed by Mr Bao Chenggang, former president of CCIGS, who added that Chinese engineers should focus more on design methods for geogrid stabilised ground structures, and not consider geogrids as a commodity sold by the m2.
Other papers and comments included Ms Ding, from Changjiang River Committee, whose work on river affected soils was demonstrating the superiority of TriAx™, and Professor Li Guangxin of Qinghua University who also presented the innovation trophy for the development of TriAx™.
