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.

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.

In this project several variants were developed, some of which were based on the French EME (“enrobé à module élevé”). After extensive testing in the laboratory ten variants were laid in 2006 on a heavily trafficked section of the E19 between Brussels and Antwerp. This was followed by the drafting of recommendations and performance specifications for this type of asphalt mixture, in cooperation with the Flemish department of mobility and public works (MOW). All information on this project can be found in a research report (CR43/07) published by BRRC.

Two-layer porous asphalt

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).
