Abstract
The desire to develop more sustainable infrastructure, including pavement structures and materials, is ever increasing. Using recycled plastics in asphalt concrete has gained significant attention in recent years, despite having been trialed and offered by various companies since the 1980s. Although some solutions are as simple as shredding up milk containers, bottles or crates and adding them to the asphalt concrete production plant, MR6 and MR10 are commercially available recycled plastic products that have been produced under a quality assurance system since 2016. These products have been tested using various asphalt binder and mixture tests commonly specified in the United Kingdom, the United States and Australia. Comparisons to unmodified asphalt binders were performed using a range of dense graded and stone mastic asphalt concrete mixtures, as well as various grades and unmodified asphalt binder. MR6 and MR10 generally increased the resistance of asphalt binder to flow and the resistance of the asphalt concrete mixtures to deformation. Significant asphalt binder ductility and elasticity was introduced, but the effect on asphalt concrete crack resistance was either moderate or not significant. There was no significant change to asphalt concrete moisture damage resistance, but the stiffness of various asphalt concrete mixtures increased two- to three-fold. Overall, the general effects of MR6 and MR10 were found to be similar to the effects associated with conventional polymer modification of asphalt binders and asphalt concrete mixtures, particularly those associated with the plastomeric polymer EVA
