Incorporating electronic waste (E-waste) in a new asphalt mixture is a subjected connected to the recycling process of PCB (Printed Circuit Boards), in which PCB waste is turned into a powder. The aim of the paper is to present the performance of the new asphalt pavement obtained by using PCB waste to substitute lime filler in a share of 100%. First, laboratory analyses are performed to determine the composition of PCB. Then, the feasibility of using PCB waste in the asphalt pavement industry is analysed in a series of laboratory investigations conducted on asphalt concrete BA16 rul 50/70 (AC16) that is a standard asphalt mixture in Romania. The following tests are performed on the new material: cyclic compression-dynamic flow, rutting test, and Marshall Stability and flow. The conclusion after the first experimental stage of this research is that the mixture containing PCB is softer than the control/witness mixture containing lime filler. Further investigations regarding the use of E-waste in road asphalt pavements will be conducted to find a way to reduce the use of new raw materials in the road construction industry.
