This project (1st August 2007 through 31st July 2010) was funded bij Flemish Agency for Innovation by Science and Technology (IWT), and was completed jointly by the University of Leuven (KUL) and BRRC. The experimental field research for this project was carried out for the greater part on regional road N9 between Ghent and Eeklo (Belgium).
The project comprised several research actions.
The object of this test is to determine the mass per unit area of geotextiles, geogrids and related products. The specimens are cut, weighed and measured as specified in standard NBN EN 965 Geotextiles and geotextile-related products – Determination of mass per unit area.
The glass fibre content of glass fibre grids is determined by the calcination method: small specimens of 2 to 20 g are placed in muffle furnace set at 625 °C, leaving only the glass fibre as a residue after heating. A glass fibre content is calculated from the masses of each specimen before and after calcination. The whole procedure is performed according to standard NBN EN ISO 1172, method A.
