Abstract
The utilisation of waste is a key approach to moving towards a sustainable environment. A lot of research is going on about different waste materials to make them reusable for various activities in the construction industry. Recycled concrete aggregate is one of the industrial wastes that can be used as a base and sub-base course material in the construction of roads. Previous studies explored various aspects of its performance to minimise the use of natural aggregates. In this study, experimental results of consolidated drained triaxial tests of recycled concrete aggregate are simulated on PLAXIS 2D software considering the Hardening soil model with small strain and NorSand model. The experiments are conducted under 40, 70, and 100 kPa cell pressure. The comparison between experimental and numerical data of recycled concrete aggregate indicated that the NorSand model works better than the hardening soil model in terms of capturing stress–strain with post-peak softening behaviour.
