According to research literature, there is a consensus on the higher stiffness and consequent resistance to rutting of recycled plastic modified asphalt mixtures. However, the low-temperature performance is yet to be confirmed. According to this paper's two case studies, it can be deduced that: 1. in line with the literature, the addition of the recycled plastic asphalt supermodifier increases the stiffness, which is necessary for design targets and resistance to rutting; 2. the presence of the recycled plastic asphalt supermodifier would not impact the resistance to low-temperature cracking characteristics and the difference with the reference mixture is insignificant. |
