Title (EN) A PAVING WITH A POLLUTION-ABATING ACTIVITY AND A PHOTOCATALYTIC MIXTURE FOR ITS PREPARATION
(FR) REVÊTEMENT DE SOL À ACTIVITÉ ANTIPOLLUTION ET MÉLANGE PHOTOCATALYTIQUE POUR SA PRÉPARATION
Abstract: front page image
(EN)A new photocatalytic composition is described that is designed for percolation in road surfaces. The composition contains no aggregates, but consists of cement, a photocatalyst, a superfluidifier, a viscosity modifier and an antifoaming agent, in suitable proportions. The composition is applied to porous open-graded asphalt courses, completely filling the cavities down to a thickness coming between 30 and 50 mm. The treated asphalt acquires a strong, durable photocatalytic activity, even when it is submitted to heavy mechanical loads and adverse weather conditions, as in the case of road surfaces in and out of town, liable to intense traffic.
(FR)La présente invention concerne une nouvelle composition photocatalytique qui est conçue pour la percolation dans des surfaces de route. La composition ne contient aucun agrégat, mais est constituée de ciment, d’un photocatalyseur, d’un superfluidifiant, d’un modificateur de viscosité et d’un agent anti-mousse, dans des proportions appropriées. La composition est appliquée sur des étendues poreuses d’asphalte ouvert, remplissant complètement les cavités jusqu’à une épaisseur comprise entre 30 et 50 mm. L’asphalte traité acquiert une activité photocatalytique forte et durable, même lorsqu’il est soumis à des charges mécaniques lourdes et à des conditions météorologiques défavorables, comme dans le cas de surfaces de route d’entrée et de sortie de ville supportant une circulation intense.
