ASPHALT CONCRETE MADE OF AGGREGATES AND WASTE DERIVED FROM GLASS AND RECYCLED PLASTICS AND PROCESS FOR PREPARING THE SAME

The invention relates to asphalt mixture materials to be used as a single basic and connecting road carpet layer, which, in addition to conventional mineral aggregates, also comprises granular particles of glass waste and plastics wastes regardless of the resin identification code and to a process for preparing the same. According to the invention, the materials have the following compositions: 1. material with total replacement of natural aggregates, composed of glass waste with a grain size between 0...4 mm, in a percentage of 55...70% of the total mass of the mixture, plastic waste ground to dimensions between 0...10 mm, in a percentage of 25...40% of the total mass of the mixture and at most 5% filler, and 2. granular glass waste material in sorts between 0...4 and 4...8 mm representing 15...40% of the total mass of the mixture, plastic waste ground to 0...10 mm representing 5...20% of the total mass of the mixture, 40...70% of the total mass of the mixture being conventional stone-type mineral aggregates, and the amount of filler is 3...5% of the total mass of the mixture. According to the invention, the process consists in mixing the glass together with the aggregates and the filler at a temperature between 160...180°C, after which the bitumen heated to 180°C is added and the mixture is stirred for 30...35 seconds, the ground plastic component is added and the stirring continues for another 10...15 seconds until a polymerized asphalt mixture is obtained. Invenţia se referă la materiale de tip mixtură asfaltică utilizate ca strat rutier unic de bază şi de legătură, care are în compoziţie, pe lângă agregatele minerale convenţionale, şi particule granulate din deşeuri de sticlă şi materiale plastice indiferent de codul de răşină identificat şi la un procedeu de obţinere a acesteia. Materialele conform invenţiei au următoarele compoziţii:1) material cu înlocuirea totală a agregatelor naturale compus din deşeuri de sticlă cu granulaţia cuprinsă între 0...4 mm în procent de 55...70% din masa totală a mixturii, deşeuri din materiale plastice mărunţite la dimensiuni cuprinse între 0...10 mm în procent de 25...40% din masa totală a mixturii şi cel mult 5% filer, şi2) material din deşeuri de sticlă granulate în sorturi cuprinse între 0...4 şi 4...8 mm reprezentând 15...40% din masa totală a mixturii, deşeuri din materiale plastice mărunţite la 0...10 mm reprezentând 5...20% din masa totală a mixturii, 40...70% din masa totală a mixturii sunt agregate minerale
