Exploratory study of porous asphalt mixtures with additions of reclaimed tetra pak material

The use of cellulose fibers (CF) has become a common technique for reducing draindown problems in porous asphalt (PA) mixtures, helping to increase the bitumen content and providing thicker binder films. In this research, a laboratory study was conducted to assess the suitability of using recycled Tetra Brick Aseptic (TBA) containers as an environmentally friendly substitute for virgin cellulose fibers used in PA pavements. The results obtained showed that recycled TBA material was a suitable addition for PA mixtures, providing similar, or sometimes greater, improvements than commercial CF.
