This paper details a cold recycling evaluation of 100% reclaimed asphalt aggregates without any binder addition. In this context, a series of triaxial laboratory tests was performed. Monotonic triaxial tests were conducted to determine failure resistance at 20°C, 50°C and with a specimen preheated at 50°C then tested at 20°C. Repeated Load Triaxial (RLT) tests were performed to analyse the permanent and resilient strains at 20°C, at three frequencies and with two water contents. It is found that increasing temperature causes a drop of failure resistance while cohesion is increased. RLT tests reveal that higher water content implies higher strains, as well that water content presents a higher impact on resilient behaviour than low frequencies. Finally, the non-linear elastic Boyce model was used to describe the resilient strains. Total stress and effective stress calibrations were performed with a measurement of the initial suction. Eventually, these effective stress calibrations were performed with one set of parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
