    The use of plastic wastes as an alternative to virgin polymers can be a remarkable environmentally
    friendly idea for road paving construction or rehabilitation. Therefore, this study aimed at assessing
    the potential benefits of modifying a conventional 35/50 penetration grade bitumen, with uncontaminated
    waste polymers (ethylene vinyl acetate and high-density polyethylene) carefully selected from
    plastic recycling plants. A virgin polymer (styrene-butadienestyrene) was also used as reference material
    since it is the polymer most commonly used for bitumen modification. The performance (physical,
    storage stability, and rheological properties) and morphologic characteristics of the different waste polymer
    modified binders were thoroughly evaluated and compared with those of the 35/50 bitumen and the
    virgin polymer modified binder. It was concluded that recycled EVA and virgin SBS modified binders
    could perform similarly, namely regarding their viscosity and rheological properties. Furthermore, EVA
    modified binder presented slightly better storage stability probably due to its homogeneous dispersion.
    The recycled HDPE modified bitumen reveals some promising physical properties (associated with
    rutting resistance), but it presents the worst resilience and creep recovery. The outcome of this work
    is the development of new asphalt binders modified with waste polymers as reliable alternatives for road
    paving activities due to their excellent performance, comparable to that obtained with the most
    commonly used virgin polymer.
