Abstract (en)
The system for obtaining dense cold bituminous coating comprises a mixer (1), transportation (2) for the addition of large elements, transportation (5) for the addition of fine elements (GF), transportation (4) for adding a first emulsion and transportation (6) for the second emulsion. Large elements (GG) are introduced into the mixer. A measured first emulsion (EBPF) is then introduced to obtain a homogeneous and uniform binding film on the large elements. A measured second emulsion (ES-BPF) is introduced to obtain a total coating of the mixture. The second emulsion is obtained from the first emulsion during mixing by adding a cationic aqueous agent (SV). This cationic agent comprises additives which enable obtaining a second emulsion with a viscosity between 3 and 1000 STV. The cationic agent is measured in the ratio of 0.5 to 2% of the mixture of large elements and fine elements.
Abstract (fr)
Des enrobés denses bitumineux sont obtenus à froid par un procédé, et un dispositif pour la mise en oeuvre de ce procédé, selon lequel des gros éléments et des éléments fins d'un matériau à enrober sont introduits séparément dans un malaxeur (1), l'introduction des gros éléments étant suivie d'un ajout d'une première émulsion bitumineuse et l'introduction des éléments fins étant suivie d'un ajout d'une deuxième émulsion bitumineuse obtenue de la première émulsion par ajout d'un agent. <IMAGE>
