abstract = {This research aims to determine if the observed improvements using polyethylene (PE) waste in asphalt binder
translate into better performance at the asphalt mixture scale in the laboratory environment while overcoming
the stability and homogeneity issues experienced at the binder level. This is accomplished through a round-robin
multinational experimental program covering four continents, with the active participation of eleven laboratories
within the RILEM TC 279-WMR. PE modified AC16 mixtures were prepared employing the dry process
using local materials with the PE waste provided by one source. Various mechanical tests were performed to
investigate the compactability, strength, moisture sensitivity, stiffness and permanent deformation. Compared to
the control mixtures, the following observations were made for PE modified mixtures: easier to compact, lower
time dependence of stiffness, higher elastic behavior, lower creep rate, and higher creep modulus. Furthermore,
cyclic compression test results showed that the resistance to permanent deformation is improved when using PE
in asphalt mixtures, whereas the wheel tracking tests showed relatively similar or better results when 1.5% PE
was added to the control mixture. The wheel tracking test results in water showed an increase in deformation
with increasing PE content. The interlaboratory investigation showed that the use of PE as a performance-enhancing additive in asphalt pavements is a viable, environmentally friendly option for recycling waste plastic
and could potentially reduce the use of polymer additives in asphalt.},
