Abstract

More effective and sustainable use of natural resources besides the mitigation of environmental impacts induced by their extraction could be achieved by reusing construction and demolition (C&D) materials. C&D materials are increasingly being used in pavement bases/subbases as a reliable alternative to virgin quarry materials. The behaviour of flexible pavements under dynamic loads conveyed from traffic load can be evaluated in the laboratory by the repeated load triaxial test (RLT). This research study aims to evaluate the macro- and micro-mechanical interaction and underlying mechanisms of the behaviour of unbound recycled concrete aggregate (RCA) materials under RLT test using discrete el..
