ECO filler is one of our certified products released during the thermal treatment of tar-containing asphalt. Fillers are used in the composition of asphalt. During the cleaning process, flue gases and cooling air are generated to cool the minerals. Both contain particulates. The cooling air is sucked through a ceramic filter that separates the coarse ECO filler (0/500 µm). The flue gases released during combustion pass through a fabric filter, where the ECO filler is separated.
ECO filler has latent hydraulic properties. Combined with various cement types, these contribute to developing strength. ECO filler is certified on the basis of both BRL 1804 and BRL 9041. ECO filler is therefore a certified sustainable product that can be used as a filler in the production of asphalt and concrete.
