Abstract

L'invention concerne un matériau de revêtement de sol en asphalte mixte, déposé et mélangé à froid et son procédé de fabrication. Le procédé de fabrication comprend les étapes consistant à : niveler un revêtement en béton bitumineux (AC) existant posé sur une surface de route, le concasser pour obtenir un laitier de béton bitumineux, puis le recycler ; y ajouter un agent d'adhérence d'interface et effectuer un mélange préalable à froid pour enrober et durcir le laitier de béton bitumineux, de façon à faciliter la fusion et la liaison de celui-ci et d'une substance à base d'eau ; ajouter un retardateur pour le mélange à froid, de façon à ralentir la vitesse de durcissement du laitier de béton bitumineux soumis à un mélange préalable à froid ; puis ajouter une résine photodurcissable à base d'eau pour le mélange à froid, de façon à faciliter la liaison et la cimentation des diverses particules de matière première ; et achever le procédé de fabrication d'un matériau de revêtement en béton bitumineux au moyen d'un mélange préalable à froid, ce qui permet au matériau de revêtement en béton bitumineux d'être chauffé sans aucun combustible, autrement dit, le niveler sur une surface de route prédéfinie par pose à froid. Par conséquent, les objectifs de réduction des émissions de dioxyde de carbone, de chaleur, et autres, ainsi que la diminution de la consommation d'électricité sont atteints.
