abstract = {The main goal of this study is to evaluate the field performance of crumb-rubber-modified
asphalt mixtures used as a surface layer on high-volume traffic roads. For this purpose, several road
sections were constructed under different climate conditions and using control mixtures (manufactured
with traditional SBS polymer-modified binders) and crumb-rubber-modified mixtures. After
the construction of the different road sections, cores were taken at different periods of their service
life (up to 63 months) and they were tested in the laboratory in order to assess the evolution of the
density, stiffness and fatigue resistance of the layers. Based on the results obtained from tests, it can
be concluded that under real severe traffic and climate conditions, asphalt mixtures manufactured
with crumb-rubber-modified bitumen offer ageing and mechanical performance very similar to that
offered by asphalt mixtures manufactured with traditional SBS-modified bitumen. Based on these
considerations, this application can be an interesting solution to minimize environmental problems
caused by end-of-life tires in landfills.},
