Test for the determination of glass fibre content

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.

Test for the determination of mass per unit area

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.

Core Tasks (1)

>>

This project originated from the search for an alternative to conventional porous asphalt, which, while retaining the many advantages (acoustical properties, drainability, skid resistance, resistance to rutting) of this type of mixture, was required to reduce or limit its disadvantages (winter behaviour and durability).

Cold-mix asphalt

The advantages of cold-mix asphalt are mainly environmental: energy savings (no heating of the binder or the aggregates) and less pollution (dusting during the manufacture of the mixture).
