Use of plastic waste in materials for road pavement construction and improved subgrade

Bartłomiej Krawczyk , Piotr Mackiewicz , Dariusz Dobrucki


The article presents research on the possible use of recycled synthetic materials (plastics) in production of new asphalt mixtures and cement-bound materials intended as road pavement layers or improved subgrade. From technical and economic perspective, plastic waste constitutes an alternative source of materials that may, after adequate processing, replace classic materials used in road construction. The first stage of the research encompassed tests of bitumen containing dissolved plastic and tests of plastic aggregate, including comparison of the obtained results with current requirements for materials used in asphalt layers. Tests were also performed on an asphalt mixture in which mineral aggregate had been replaced with recycled plastic aggregate. The second stage of the research encompassed strength tests and frost resistance tests of cement-bound materials containing an addition of plastic waste. Possibilities and limitations of use of such materials were analyzed. The obtained results indicated that it is possible to use plastic waste in materials intended for road pavement layers and improved subgrade. Considerable economic and environmental benefits were noted.
