ASPHALT CONCRETE WITH AGGREGATES AND WASTE DERIVED FROM RECYCLED WASTE GLASS AND WASTE PLASTICS AND MANUFACTURING PROCESS

The invention describes the compositions and the process of obtaining an asphaltic concrete for a single base and binder course (layer) of the road structure, composed of a bituminous mixture, containing aggregates derived from crushed and sorted recycled glass 0/4 and 4/8 mm and shredded plastic 0/10 mm. The new material is made up in two recipes: with total or partial replacement of conventional mineral aggregates: sand, rock aggregates and filler. The recipe partially replacing, but at least 20%, the conventional mineral aggregates, meets all the requirements according to AND IND 605-2018, required for the roads of technical class 3, 4 and 5.

The process of obtaining the new asphalt mixture material is characterized by the fact that the glass is mixed together with the aggregates and the filler at 160-180? C., bitumen heated to 180? C. is added and, after mixing the mixture for 30-35 sec., the shredded plastic constituent is added and further mixed for 10-15 sec., resulting in a polymerized asphalt mixture.
