Evaluation of the Performance of Two Australian Waste-Plastic-Modified Hot Mix Asphalts

The construction of hundreds kilometres roads around the world every year results in consumption large amounts raw materials and depletion natural resources. In addition, technologically advanced countries such as Australia are currently facing a major issue regarding waste produced daily by their citizens. disposal these is critical faced municipalities modern cities. Currently, using civil engineering great interest to researchers industry. This study investigates impact polyethylene terephthalate modify asphalt mixtures following Australian design guidelines criteria. Different types used investigate determine mechanical properties modified mixtures. Marshall stability, flow, quotient, wheel-tracking tests were tested. MQ test exhibited significant improvements when PET SMA AC It can be seen that 8% mixture with highest stability 19.78 kN. lowest rut depth was about 2.08 mm for samples PET.
