Effect of freeze-thaw cycles on RAP/natural aggregate unbound mixtures properties

This paper presents an experimental study to evaluate the effect of freeze-thaw cycles on performance properties of reclaimed asphalt pavement (RAP)/natural aggregate mixtures for the construction of unbound base layers. A californian bearing ratio test and repeated load triaxial test were carried out on RAP and crushed limestone mixtures with varying RAP content on standard samples and samples exposed to freezethaw cycles. With an increase in RAP content, the sensitivity of the mixtures to freeze-thaw cycling is reduced, but only up to certain RAP content
